I Can't Stop Checking/Feel Worthless

I cannot stop checking my PC. I posted yesterday about struggling and today it's even worse. I have so many voices in my head saying the world is going to end if I don't make sure everything is plugged in or if my screens have no blemishes. I got a new monitor last weekend and I think it made me get extremely triggered this week...

I feel like an absolute worthless pos because I can't get this under control. I hate how I feel and I just want to cry and sleep to avoid everything. Idk where to start with getting more help. I take mess for anxiety, but I hardly feel like they work and I have to wait to see my psychiatrist until next week...
