TTC and mental health

Personal post but I need some advice.

I suffer with severe anxiety and depression and am currently not on any medication as been trying to get pregnant with my husband since March. Nothing has happened yet apart from loads of bfn!!!

I am really struggling again with my depression and have hit a low, not just because I haven't conceived yet but other personal things too....and some medical issues that have been going on for about 3 years! I just don't know what to do. Does anybody else suffer from any mental health problems? How are you coping? Are there any meds that are safe to take while ttc and whilst pregnant? The NHS are unfortunately not being very helpful with my ongoing problems!

Thanks
