Antidepressants

Going to my Dr. This week about my anxiety/depression.  These hav been ongoing issues for me and while I have "emergency" Ativan I have always avoided (at least in my adult years) regular antidepressants because I'm worried about being on them and getting pregnant but I just can't keep going like this. Anyone on an antidepressant? How does it affect your pregnancy? And how does it make you feel in general?? I've finally come to terms with the fact that I can't be a good mom if I hate my life.
