Anxious or Depressed? Or both?

So, I have been having serious trouble figuring out what has been wrong with me over the past six weeks and I'm hoping for some help.

The abridged story: about 6 months ago, I started to notice a lack of joy and a slight increase in anxiety. I wasn't concerned and quickly forgot about the little incidents until it became more and more obvious that something was off. I felt emotionally distant from my (now ex) girlfriend, despite her being pretty awesome. I, for whatever reason, had horrible horrible anxiety attacks (bed ridden) for a week when I realized that I needed to break up with my gf (this is not like me, I've dumped and been dumped enough to be a pro). After I broke up with her, I felt relieved but immediately became panicked when I wasn't upset or crying about the situation. I started to have a wierd fog with trouble remembering things and a lot of trouble having fun and talking to people. I still went about my life and nobody really noticed anything wrong despite me constantly obsessing over whether or not I was going crazy. I haven't had any attacks but I can not stop obsessing over my emotions and my weird detachment from everything. I had felt sad and couldn't cry which made me think I was nuts and burying emotion that would someday explode. At best, I had felt nothing. There's a lot going on (my dad might have leukemia, my sister might have MS, and my grandfather is dying of liver cancer) but its nothing I wouldn't normally be able to handle. I don't know what is going on. I don't have any negative thoughts or pessimism but I feel a chronic sadness in my heart that doesn't go anywhere.

Anybody got any ideas?

I am no doctor but honestly this sounds more like a physical medical condition than a mental medical condition. You may want to seek out maybe having a cat scan or MRI to rule out the possibility of a brain tumor or something along those lines. Praying for you either way

The more time I take to analyze how I am feeling and research my symptoms, I am finding that I may be afflicted with a mild for of both anxiety and depression. I do worry constantly, everything seems dulled down, I periodically feel guilty/afraid/sad for no reason, I don't feel confident, I get annoyed easily, etc etc. Despite trying to think my way out of my emotions with logic and optimism, the feelings I have do not go away.. nor does the fog.

I sought medical help and was prescribed budeprion which just made me feel more afraid and sad, however, I'm going to continue looking for a good med as well as finding a counselor/therapist appropriate for me.

Thank you so much for your help!
