Overwhelming feeling I’m gonna die

I’m 23, I have two daughters, aged 2 and 4 months.

Lately I keep having this really overwhelming feeling that I’m going to get an illness like cancer and die before my girls are old enough to really remember me, and I can’t shake it.

I’ve been having blood when I go to the bathroom which I always knew was a red flag for bowel cancer, but I was diagnosed with colitis. I’ve also had some breast lumps which they said were fine. I keep having this voice in my head tell me to get a smear test. Now, I’ve noticed a change in a mole I’ve always had.

I keep having dreams about being diagnosed with cancer.

It’s almost at the point I’m not afraid of the thought of dying but I’ve come to accept it as matter of fact. The thing I’m afraid of is who will take care of my kids the way I would.

Has anyone experienced something like this?
