Ever since I was a teenager and I started going through puberty, I've felt unfulfilled in life. I used to think (and currently think) that it's because I'm single and I don't have anyone with whom I can be close. Sure, I have a couple of close friends, and my family, but it's not quite the same. I also have lots of hobbies and things I like to do, I go to a good university and while my grades aren't great, I'm trying hard. I don't drink, don't do drugs, and am generally quite happy. However, when I'm by myself, I often find my thoughts drifting to the fact that I don't have a partner. The feelings of unfulfillment did briefly go away when I was with my ex for the first time, but they came back a couple of months later. Even so, I still find myself thinking that that's the reason for this emptiness I feel. I honestly can't think of any other reason why I might be feeling this way, but I know that fixing this problem won't solve it as it didn't work last time. I don't know what to do and I don't know who to talk to.
