If you are interested in the theories behind depression being frequently comorbid to fibro:
There are neurotransmitters that are low in fibro, which are also low in depression.
Also, both conditions have more pro-inflammatory cytokines.
It's kind of been assumed that anti-depressants helped by providing re-uptake of neurotransmitters, but for many years, it's also been known that anti-depressants can reduce the numbers of pro-inflammatory cytokines. (I don't tolerate htose meds, or they don't help)
It has been observed that some cases of depression were precipitated by an injury involving inflammation. If you've read much research about
inflammation in fibro, then hopefully you kno that there are numerous kinds of pro-inflammatory cytokines found in fibro.
One of my favorite people to follow, a researcher from Belgium, is Michael Maes. He seems to love to debunk "in your head" theories. Like one about
graduated exercise therapy (GET) and cognitive behavioral therapy (CBT) for Chronic Fatigue Syndrome. He has done a very early fibro study on one inflammation marker and he also has this interesting study about
autoimmunity to 5-HT in depression patients.

And he has done interesting research about
how leaky gut (official name: intestinal permeability) lets things out of the gut, that shouldn't be anywhere but the gut (or in the toilet, lol). And that starts some immunity processes, and he connects that with depression. I'll try to find a link to that something aout that study and edit it in. I think I have posted it here before.

A couple of things that help me with depression:
I sometimes take a supplement called 5-HTP. It has been used in a fibro study. It's a precursor to the neurotransmitter serotonin, which is low in fibro. However, many meds will affect serotonin levels, and if you get too much serotonin, you can go into serotonin syndrome, which is bad. Wikipedia has good info on that. The tricyclic antidepressants like amitriptyline and nortriptyline are listed at wikipedia as affecting serotonin (see serotonin syndrome, I think). I happen to know that I tested in the "low" range in a urinalysis of neurotransmitters (pharmesan labs kit from my psychiatrist, and I shipped the very small sample to pharmesan labs), plus I take a relatively low dose of amitriptyline. It's wise to read up on all this, and know the signs of serotonin syndrome, if you are thinking of trying a supplement. Alternatively, since neurotransmitters are made from amino acids, be sure to include enuf protein in your daily diet. I recently included in a post some info about
genetic polymorphisms ( and I think I spelled it wrong) that indicate there is an enzyme deficiency that affects making neurotransmitters.
If you internet search mood disorders (or depression) and hypothyroidism, you'll see that being low in thyroid hormone can affect us. It makes a big difference to me. My testing for years was only for TSH, Thyroid Stimulating Hormone from the pituitary. Tha's what most doctors were taugh, but it is wong. Once I got a better doctor, I had Free T3 and Free T4 and reverse T3 run also. A video lecture I recently listened to said to also test for Total T4, which is "bound". "free" means available. I may have had that tested also, but perhaps it's OK and never is mentioned to me.
Getting off of the typical prescript
ion meds for hypothyroidism, levothyroxine, synthroid, which contain only T4 hormone, and switching to something with some T3 also, really helps me. Mine is a compounded mix of T3 and T4. Some people find their body does a poor job of removing the fourth iodine molecule, and converting the T4 into T3. T3 is the real power-horse thyroid hormone. I think (do we trust my memory? i think so) that T3 is 8 times stronger than reverse T3, so if you have too much reverse T3 taking up too many thyroid receptor spots, you're going to be slowed down. And every cell needs thyroid hormone to instruct it on its metabolism, and that includes your brain.
And two other things that can help my depression are regular exercise, usually walking or a gentle hike, and I can also benefit at times from a light for seasonal affective disorder (SAD). I bought a really big, really bright one. Some days I have to have a white gauzy scarf over it, cuz it seems overwhelmingly bright, but if you read the specs on them, some require that your face be 18-19 inches away. My light can be further away, and me, comfy, in a nice soft chair.
Post edit, 4 years later. Now I would not use the SAD (seasonal affective disorder) light that I used to use. Instead I strive to get more of the rays of the rising sun. The actual rising sun at the equator. Here in a southern U.S.
location, i may not get my sun until 8 or 9 a.m. Early sun has short red frequencies (light waves, not particles)that are a match to 3 different frequency light windows of our mitochondria. (As per neurologist Dr Jack Kruse. He says this will help raise dopamine, while helping mitochondria function, which is bigger goal. Man made lighting tends to be blue light particles.
Now I would not use amitriptyline. It is toxic to mitochondria. I have seen a study abouf it from Cordero et al (they Also have fibro studies), and another team's study (can't recall any authors) and it is on "mitotoxic" lists. Because nortriptyline is like a step away from amitriptyline I do not trust it. Drug comoanies do not have to prove that meds are not mitotoxic.
Can't remember where I read this, but having more inflammatory cytokines can result in worse conversion of T4 thyroid hormone to T3. And TSH is also made in places other than the pituitary. I sure have learned a lot more in the last four years of patienting online.
