Am I overthinking this?

Hi, should I be angry or am I the asshole

So last weekend me and my boyfriend went to our friends house and we told shrooms (penis envy) 1.75g each which is considered a heroic dose if I’m correct. the night went well (duh) until my boyfriend went to the bathroom and he then passed out while peeing and then got back up and was acting fine then passed out again and start spazzing out for a bit, me and my friends went to the bathroom helped him up and had him in recovery position and we then noticed he bashed his eyebrow open and while this was happening we were still in the high.
after he passed out the 2nd time I thought he died and I went into a start of shock and I was uncontrollably pacing back and forth the living room having a panic attack thinking we was going to jail and he was dead and I was sad because it was my boyfriend that it had happened to. Then my boyfriend came to comfort me it didn’t help because I had at the time thought he was still dead but I then realised he wasn’t actually dead I just thought he died for 3 minutes😭 (he only passed out)
then a hour or so later he had some food and juice and was settling on the sofa while him and one of the friends were laughing about it.
I was still in a state of shock and I wanted to take him to the hospital to get him checked up because I still then thought he died and came back to life (he didn’t) and he was telling me no he is fine and that I’m overreacting.
I spoke to one of the friends in private and we agreed to call the hospital ONLY if my boyfriend agreed so I went through asked him he refused then I said something I never thought would come out my mouth “I’m going to break up with you if you don’t let me take you to the hospital” then he and one of our friends was like no that’s not okay to say so I apologised and went through to another room as I had realised I shouldn’t of said that then my boyfriend came through and comforted me and that’s it we went to sleep all good.

now since that day my mental health has been terrible. I have had terrible night terrors of being pregnant and my baby dying, my boyfriend with another woman, and one of my friends trying to kill me
so I’m scared incase it turns into something psychotic as earlier this year I had dealt with family and pets and friends dying and I made me super depressed and also sent me into some sort of manic psychotic behaviour and I had then been put on meds

today I had spoken with my boyfriend about him and one of the friends we hung out with the last weekend and they were talking about taking shrooms again and that made me nervous prior to what happened last weekend. I had said I don’t feel comfortable with you doing them without me right now due to the last time and he told me “I’m a fully grown adult I can do what I want” and I can agree with him partially on that but I still don’t know if I’m in the wrong.

Im totally aware I over reacted and that I’m just worrying because it is my boyfriend but I don’t think he is also understanding how it had affected me and isn’t taking my feelings into consideration, I had previously spoken to him trying to understand how I feel and trying to compromise on things but it hadn’t worked, I’m scared this takes a toll on our relationship and my mental health just getting worse.
