Be easy on yourself some, you aren't a bad person or a failure, that is the illness talking, not you as a person. It's good you are reaching out for some support.

It sounds like you have probably been at your job for awhile, hopefully at least a year? Please look in to FMLA and/or short-term disability. It is there to help you.

it sounds like you might benefit (a lot) from taking a break short-term, and can take it from there after having time to step-back for a minute. Maybe a medication adjustment may help, maybe seeing providers or someone new may help, maybe just having some time off will help.

Don't quit the job though. You may be right that a remote job may end up being best for you, but right now probably isn't the time to make any big decisions.

When do you see your healthcare team next?

How are/have things like sleep, nutrition, hygiene, etc been going?
