Is it normal that i've attempted suicide and have these side effects:

Some background: beginning of summer last year was when this happened. I had gotten into a really stupid argument with my friends and we weren't talking to each other. I'd left any online communities I was in a few weeks ago. I was isolated as shit. I also had nothing to do. I'd just kinda pass every day watching netflix playing video games and jerking off.

One night, I was rewatching community, and I was in a bad place. I thought I'd probably end up being another drone in the future, living a shell of a life in corporate america with no real decision making power or purpose or some shit. I had no one to talk to, I had just reasoned away anything to look forward to in life, and really had nothing. There are more reasons but naming everyone explicitly puts me in a bad place.

The community theme song played, and there was one lyric "I can't count the reasons I should stay // One by one they all just fade away". This lyric just kinda stuck in my mind. Look away if you're squeamish. I took an iphone charger, and made it into a noose. I tightened it around my neck. I was about ready to hang it on the ceiling, when I decided to check the knot. It wasn't satisfactory for me. So I took a thick audio cable and made a stronger noose. Before hanging it from the ceiling, I changed my mind (the view from halfway down).

Then I just remember feeling nothing, and then a wave of emotion, like that had been all that saved me. A month later I'd recovered mentally, I had a brand new outlook on life, that I continue. I live in the moment, for the fun, the laughs and the emotion. I try not to think about the future (though I do suffer from anxiety) too much.

Whenever I hear the community theme song or think about ending up working in corporate america, hell even watching community, any lines of thought from that night, I just get this weird feeling. Time slows down. I feel detached from the situation. I feel an internal pain in my chest, below my heart, my lungs turn to ice. It can be almost paralyzing, it was the first few times it happened.

I haven't told a single person this story, but I know talking about things helps. I don't know why I posted here, but ig is my experience after this normal? And maybe further, what do I do?
