Late period

I haven’t had my monthly in 41 days. I’m ridiculously emotional, it’s been very hard on my mental health. I’ll have cramps like it’s coming and it doesn’t. The longest I’ve gone without having it was a month.. I was told since I missed a month I’m also gonna miss this upcoming month for it and was told that bec I’m stressed is causes it to be late but this is really annoying. I’m annoyed all the time, depressed more than usual and having cravings triggers my Eating Disorder. Idk if it being THIS late is normal orr >.<
