Hey - @thatsweeneyguy.
Please try not to be too hard on yourself. I too struggle with depression and anxiety. I know where you're coming from. It really sucks!
Everything is temporary, especially these bad feelings that you're having. I've found that engaging your senses can be good therapy for sucky feelings like this. This blog entry? Probably good therapy. When I was a kid, smashing my hand into a wall. (Not recommended.) I also played immersery video games. Both made me feel better. Why? It engaged the senses away from the feelings of anxiety.
So if you can figure out some way to change and engage the senses, you'll probably help yourself to feel better. The more senses, the better. So, doing something like taking a walk while listening to awesome music and eating an ice-cream cone?
Also, if you ever want to talk - buzz me over at Discord! Good luck, dude.
