Hey, this is embarrassing to post here but there's no one I (20F) can tell at the moment

I am worried that I am about to have a nervous breakdown or psychotic manic episode, either of which I have had before. Not nervous breakdown as in panic attack, but complete collapse. I'm sure most of you know what I mean.

There is just so much right now and I can't do it. 

Last week was terrible for me mental health wise; I slept more than 12 hours every day, I smoked weed every night (not unusual), I punched a wall to relieve some emotions which I've never done before, and right now no one is texting me back at all and my boyfriend just said he's worried about us.

I have a decent amount of caffeine in my system, a bit of delta 8 THC which I vaped about an hour ago to relax a little bit, and prescribed adderall. This isn't a medical reaction thing but I'm just putting it out there

I need help. When do I need to go to a professional about this? How do I tell my friends and loved ones without scaring all of them to death? Is there anything I can do to stop or slow the descent? Anything and everything would be really appreciated, but please don't tell me scary things
