Tw: gun/robbery

Yes, before we start I am going to therapy but no amount of therapy can save me from how I feel about this job.
We had an attempted robbery last Sunday in the drive thru while I was the closing shift. A man pulled a gun on the teenage barista I had in drive and luckily she ran away and he drove off before the cops came. However I had to walk her out of the panic attack that followed, deal with the asshole cop and calm down the other 3 partners in the store. My manager and temp. DM came an hour later but said I had to still close down the store. So I had to make everyone, other than the girl at the window, continue to work but I let them go home a little early and I finished the floors. No help from my manager.
We all feel terrible for the girl who was at the window and she hasn’t left her house since. The amount of guilt I feel is beyond what I can explain here, because I wish it were me and not the teenage girl who is also missing her graduation this year. However, no one in the store has asked how I am doing and I feel selfish for this but it hurts. My SM let me take the next day off and asked me how I was doing but that was the last of it, she said a therapist from Lyra was coming but he has yet to show. At our store meeting, in front of everyone, she said “Yes that was bad day but you weren’t at the window, so and so was and we a hope she’s doing okay” and I was like cool, cause before the cops showed we all thought he was going to jump through the window and we were all cowering in the back so of course I don’t have PTSD from that, and it’s totally cool to say we don’t have any trauma in front of other people!
I’ve fucking had it. I broke down to my boyfriend because I said that if I had just quit years ago, like I’ve wanted to, I wouldn’t be in this situation. We’ve had a line around the building since I’ve come back and all
my manager can do is walk on the floor and ask why cars are red. She schedules me to close with 2 people and than has me in at 7am the next day, when I’ve already told her not to do this. And then when I come in she tells me I can’t leave the store looking like however I left it and that I should stay as long as it takes even after I had already stayed an hour and a half after closing.
And the thing is, I’ve worked in 3 different states at 7 different store and it’s all the same shit. This isn’t my third place because there are a thousand other places I’d rather be. I hate our regulars and I’ve almost never enjoy talking to a single one of our customers. My coworkers, not partners, are catty and mean. I’m only here because I live in the US and can’t afford health insurance without so I’m fucked.
This job has chewed me up and spit me out and nothing about it has made me a better person. I’m bitter and angery and I’m told it’s my fault when I’ve been called a bitch more times I can count by customers and the homeless people who shoot up in the bathroom who I have to kick out.
I just wish corporate would stop pretending that this job was gods gift to this earth. It’s soul crushing and I would never urge anyone to apply.
