Feeling helpless

Seems that every anti-depressant I take makes me feel worse.  I still have the head swimming sensation.  It has actually gotten worse....  When I sit I feel like I am moving and when i lay down I feel like I am falling..... It sucks......
I go to a new doc on monday cause I can't afford the one I had been seeing at the hospital.  Hopefully he will have some good advice.  I didn't take the wellbutrin today cause I didn't have any.  Plan to pick up a couple tomorrow.  I don't know whether to take them or not.  Since everything seems to get worse with the anti-depressants.  
I feel lost and helpless.  Like everything I try doesn't work.  I've only taken the wellbutrin for 7 days and I feel physcially horrible.  I don't feel depressed.  I do feel alittle anxious.  I also feel a little irritable and can get mad pretty easily.  Not sure what all that means.  Or if it means anything.  
I just hate the thyroid!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
That is when my life went to hell....  And it hasn't came back yet?????????????????
