Depression from meds?

I stopped metformin abruptly and started birth control around the same week I stopped the metformin, and so suddenly and intensely felt so much pain like I was dying. Its been 3 months and I haven't gotten better, I used to be so happy and hopefull now I feel completely hopeless, uneasy, and cannot enjoy anything. Will I ever get better??!!

I know nothing about this medicine but will make this post current so it is more visible and maybe someone can help.
