Hello, I dont know what is wrong with me but i think there is. Im 18 years old and I have many different types of thought patterns. Sometimes i feel normal and content then sometimes i feel worthless and a failure and lonely.then sometimes i feel very confident about myself. I also find it cery difficult to nake conversation with people because a lot of the time i just think that most conversation is pointless but i think this auses people to not like me and it may be the reason im lonely. I find it very difficult to change and it angers me because i know that i need to but it just feels impossible to motivate myself to talk to people because as i said im fine being on my own most of the time but then comes the time when im extremely lonely and feel useless, worthless, a waste of space, unmotivated for anything, and extremely depressed. Im not sure if i described it properly but what can i do?
