Always a good idea to go in to the ER and get checked out in these matters, anyway (as things can later appear to give you serious or significant repercussions later on in life; though I know that-that may be far from where your "head space" is at right now...)
Just take it from someone who's been there! I'm still very much dealing with & suffering through the consequences and the effects of my episodes / attempts, oh-so many moons ago!
All I can say is: Not Fun. . : )
24 is a prime time to have a "mid," or "quarter," life crisis. I think you'll find... that the more time you stay and talk to people on here. It is really not so different and rare - after all! Good luck & best wishes on a speedy recovery. You deserve it-
