thankfully your boyfriend sounds understanding....
yes, a support group can be helpful...
Now, perhaps your medications does not "fit" you, or it may be side-effects. Look into this...or online and see if these are side-effects of your medication.
Also, if your Doctor gives you different medications all the time... maybe this is not good, and the switches are too abrupt..
Or, maybe you also have anxiety/panic disorder or something else in addition to depression... or could it be possible that your Doc mis-diagnosed the depression? And maybe it is something else?
Maybe get a 2nd opinion, from another Doctor as well... that might be helpful.
Or could it be hormonal?
I would get a 2nd opinion... and, see if your current medications have side-effects.... and yes, support groups.
take care and I wish you all the best,
Susan
