I'm sorry, Max. Sometimes, just talking to a friend about anything helps distract from these low times. Or call a professional? Hope you're okay...
I don't know what country you're in but I'm UK based and I call crisis when I'm really low just to get talked down. Once I'm calmer I find it easier to rip off the plaster and talk to family and friends. Hang in there! You'll get through it
So been there. So difficult to get out of a gig for a breather. Do so if you need to but don't lose your friends. You are loved and appreciated. As is your strength to carry on. Just breathe if you need to.
Getting out will make you feel better, don't let the demons tell you otherwise, you'll be fine and you'll have fun :)
Sorry to hear that, Max :( Maybe call someone for help?
Talk it out. If you can't, try walking it out. Breathe and stretch. Who knows what could help...
