Couldn't decide if this should go under the 'needs support' or 'needs advice' cause i honestly need both. Let me know if i need to change it though

For Context, I've dealt with general anxiety issues since i was a young teen like most of my family. It hasn't been anything super severe in a few years, just enough to limit me and be annoying. 

However, for the past month I've been dealing with things off the fuckin wall. I'm panicking over hypothetical situations, losing sleep at night, and getting so anxious i feel sick out of completely nowhere. 

It started when I was dealing with an abusive coworker who made me feel like i was walking on eggshells. Then the stress of quitting and getting a new job, and now the stress that my new job isn't starting me fast enough and I won't have money for rent

The thing is, these things are all totally manageable. I would dread going to work when that coworker wasn't even scheduled. I just started the month and I have my money for rent set aside already. I should be fine. But I'm not fine. 

And now I'm dealing with what a lot of us agree is one of the scariest situations possible- my long term girlfriend started crying earlier while we were talking, and has told me that we need to talk about something i did to her

-But not until tomorrow-

I know why, she genuinely isn't ready to have a big conversation today, and I'm not gonna push her. But oh my god i feel like I'm falling apart. She has assured me she isn't mad and already forgives me but i have no idea how to cope. I feel sick, my head is spinning, and Im so worried about her.

I haven't dealt with anxiety this bad in so long i genuinely don't know how to cope anymore. I'm on a wait-list for therapy but until then I'm not on meds or anything. How do y'all cope? What do I do?
