Is it normal to have suicidal thoughts after a rejection??

TW: Suicidal Ideation

I was rejected 6 months ago and have tried very hard to get over her but the thoughts JUST.DON'T.STOP.

I just want to forget her. And I've not even been in contact with her since a month now. I don't want to think about how I feel; it makes it worse. Even writing this is making me cry.

>! Please help. Just make it stop. please.!<
