Let your SM know what’s going on in your life. Ask if you could take a leave of absence and if/when you’re ready to come back you could text or call them to let them know. Mental health takes priority over everything in my opinion. It’s just bean water. Just be honest with your manager. You don’t need to tell them everything, just let them know you’re not 100% and if they’re a decent human they should understand.

As for late/calling off, just try to do your part and let someone know. Running late happens, but running late to every shift or calling off often only makes it a coin flip whether or not they should even schedule you. It isn’t fair to other partners when they have to pick up the slack for someone being late.

But I believe in you! Take whatever course of action you think works best, but don’t stress out over this job, it ain’t worth it. Best of luck with everything.

If they fire you, they have to pay unemployment. Of you quit,they don't. Depends on how dire your circumstances are and whether you can afford to forego unemployment.
