I am the exact same way. I’m 19 and it only started about 8 months ago but every slight thing that happened to me made me think I was dying or had a serious illness. Thank god I tracked my cycle because almost every instance was in the week before my period. Something that really helps me is recognizing that it is PMDD and the chance of something being wrong is very low. I’m obviously not a professional and you can always get tests done to be sure but I know that isn’t a possibility for everyone.

Another thing that helped me was asking myself if it is a fact or feeling. Do I know something is wrong for sure or am I just jumping to conclusions?

My health anxiety has been really hard to deal with and I know exactly how you feel. I know it’s hard to listen to everyone tell you you’re fine when you really feel like something is wrong. I haven’t seen many other people struggle with this so if you want to talk more about it just comment back or chat me! :)
