I can’t stop crying

I’ve been struggling a bunch, I seriously don’t know what to do with my life anymore? I’ve been going on a state of mania to depression. Is this even normal? Life has been going so well lately, but I can’t find myself to be happy in it. I can’t stop acting happy either, like seriously nothing ever feels good enough for me. I just need a hug, I just need someone to talk to, to console me and tell me everything is going to be okay. I just need that special person.
