Hmm it looks to me like (but I'm no dr) that part of this depression is caused by the withdrawal. This can last for quite some time but you need to realize that this too shall pass. It always helped me to rationalize such things. About medications...it isn't even scientifically proven those neurotransmitters they affect really are the leading cause for depression, it isn't even scientifically proven why anti depressants work for certain ppl and why for others not. I am someone who reacts rather badly to all kinds of medication (not only anti depressants) and I also don't feel like the whole trial and error process, so I chose a while ago to not take any anti depressants for now. I'm not saying this is a definite that will never ever change, tho. I think talking to a dr would be a very wise idea.

I can get along with my family doc very well actually, I wouldn't even mind having her as my therapist but ehh she isn't a therapist, lol. Best of luck!
