I'm worried

I am worried. I am 21 years old turning 22 this year. I'm in a place where I feel like my period will honestly ruin relationships in my life. I never thought period hormones affect me as I am the same person as I usually am, on or off my period. But now I'm realising that actually, every time I fall out with a friend or argue or whatever it's always when I'm on my period. I never do anything drastic and then regret it, but things affect me more. And now I have this great friend who after many years I finally met up with. She had this pain in her LEFT ARM today, and being a med student, I was WORRIED and so I got a bit mad when she told me she wasn't going to go to the A&E. She caught on that I was mad when she called me, and I told her I was slightly annoyed but it's ok. I realised as close as we are she doesn't understand me as much yet. Ive had people I've lost due to negligence of either hospital staff or themselves. So she's really upset now because she feels she upset me and so I guess in a way this is our first ever little blip. And it happens to be while I'm on my period. Now if this was a guy I would have probably ended up thinking of all the other times I've been upset and thinking of a irrational solution. I don't want to lose great friends or turn into this over caring weirdly sensitive person, that's not me, and I dot want to have blips or lose people. What can I do 😞
