Mental health question

Hi ladies ... I'm having some difficulty and would like some opinions. I have a long history of severe depression and receive regular treatment with a psychiatrist. DH and I are TTC and I was given the option of going off one of my antidepressant medications to see if I could manage on less - never with the expectation I would be able to be off meds entirely. Anyway, that was about 2 months ago and I have noticed that I am having trouble functioning. I tried to ignore it for a few weeks but lately it has been much harder to ignore.. I'm in bed all the time, not showering regularly, no motivation, can't remember the last time I brushed my teeth. It's all I can do to get to work. I'm not sad... it seems to be mostly physical I guess? Anyway - I know I probably need to go back on meds but I feel this is not best for baby. Feeling quite defeated..
