Losing My Mind

Long story short, several years ago I was having my period for months at a time. I had a d&c and then didn’t have my period for over a year. Got put on medroxyprogesterone to have my periods. I stopped taking the progesterone in April. Had my first period without the med last month. When I was pmsing I felt like I was losing my mind. I was worried about my bf being mad/annoyed with me and thinking about leaving me. Once my period started all those thoughts went away. Now I think I’m pmsing getting ready for this months period and I’m back to the same mindset. I was at his house last night and started crying because I didn’t want to leave cause I just want to be with him all the time. Today I’m worrying he’s mad at me and getting annoyed despite the reassurance.

Any recommendations to help ease this mindset?

My bf is the most amazing man and has done nothing but reassure me we’re together for the long haul.
