i'm just having a hard time controlling my feels right now

I honestly feel like I have no one I can talk to anymore. My friends have moved on and have lives and it’s not fair of me to ask for their help when I’m in a crisis anymore. I just feel so alone and it does not help me to talk to strangers/people I don’t know online at all anymore. I’m feeling a lot better but I still have a hard time controlling my emotions when something triggers them to go WAY down like the world is ending. I’m trying so hard right now but processing this alone is one of the hardest things to do.
