I Am Not Okay

I feel as though I am losing myself, slipping away, and I don't know how to make it stop. It gets like this a lot, to the point where I don't even see the point in living. But I have to carry on for everyone else, and because I feel like I have no real reason to feel the way that I do. I am so angry about everything all of the time, and jealous. I can't socialise with people easily because I just can't relate, and my brain is really messed up in how it thinks about a lot of things. I'm stuck in this weird no mans land of knowing something is wrong but also feeling like nothing will change. I don't know. I haven't explained this very well, I'm sorry. I don't even know what I'm expecting to get out of this.
