Oy Vey!

Try to hang in there.  This is a rough road, but you are not the first to travel it.  I am 30 years old and was just diagnosed with MS a few months ago, after four years of doctor-hopping and being told it was probably stress.  Eventually you will figure out what is going on, and then you can focus on getting treatment and making adjustments to compensate.

Be patient with your husband.  Believe it or not, what you are going through can also be very hard on him.  My husband wavered at times during the diagnostic process, but now that I have a firm diagnosis he is quickly becoming my staunchest supporter.  It is difficult for him to understand the things that are happening to you, but that he can't always see evidence of (such as the fatigue).  Remember also that he is the one picking up the slack when you are down, which adds to his stress level. 

I hope your doctors are able to figure out what is wrong with you quickly.  Until then, just take it one step at a time, and try to remember that your family loves you and needs you.

P.S. Have you thought about replacing your PCP? 

I'm a little reluctant to say this next thing because you're in a tight spot right now. But I know it would help me, so I'm going to risk it...

Getting an official diagnosis won't necessarily make any of that stuff go away.

Maybe your husband would be more supportive if you had an official diagnosis. But plenty of people with an MS diagnosis still have a hard time communicating their fatigue or weakness or whatever to their spouses. So whether this is real (MS or something else) or whether it's all in your head (which is a running joke with me and my husband, who has MS, because in a way it IS all in his head--or at least in his head and spine..hehe), you and your husband will still have to find a way to communicate and get on the same page. Even without a diagnosis, you and your husband can set some ground rules for how you'll interact with each other.  Even though you know what's breeding tension between you, a regular trip to a marriage counselor might help you both clear the air in a helpful way, too. (I always hate when I'm struggling with something and someone recommends counseling to me...ARGH!...so I'm sorry! But I really do think it might help.)

As for all the symptoms, there are lots of ideas on these forums on how to compensate for symptoms as much as possible. Sometimes, folks just have to learn to live with a symptom, but sometimes there are things you can do to help.

My husband and I are big believers in the MS diet connection now, so I can never post anywhere without mentioning it (more apologies...I'm a proslytiser for the Best Bet Diet. I can't help myself). But there are a lot of MS diets out there, and none that I know of are actually dangerous in any way. So it's just the inconvenience of the food restrictions, which it seems would be worth it if it might help with the myriad symptoms you're struggling with or with your marriage issues. At the very least, you could consider Vit. D supplements, b12, and a gluten-free diet. Those three things seem to be huge for a lot of people with MS. Anyway, it's something that you can do entirely on your own, without a diagnosis. It took about 6 months for my husband to really get into the groove with the diet, so it's a commitment. But it has been well worth it for us. We've been on the diet for a couple of years now.

Anyway, whenever I'm feeling overwhelmed, frustrated, or helpless, it always helps if I can identify some step that I can take to try to make my life better, however tiny.

Good luck!
