All my old friends are dead

I used to use with 3 main people and the third, my ex boyfriend who was amazing, died earlier this month. The first friend died last September, the next friend in February, now the last died. It all happened in Florida and I left a couple years ago because I knew if I stayed I’d die. It’s such a weird feeling and I know it’s not their fault at all. Everyone says I’m strong and stuff but I’m just lucky. I had a place to go far far away from them. They didnt. I wish I had reached out but I didn’t. There were too many triggers and I didn’t want that in my life. But why would I think they’d be okay? I hate that I ignored his texts.
