<human>: I'm currently in a one-year relationship. We're both in our early 20s.

I'm needlessly insecure. I randomly become anxious and suddenly worry that he doesn't want to be with me/doesn't actually care about me/etc. The problem isn't just that I feel insecure, it's that I actually become overdramatic and crazy. I even take it out on him and pester him about whether or not he really cares, which is clearly emotionally draining for him. Knowing that my behavior is tiring for him adds even more stress because then I start to worry that he'll leave me because of my insecurity. Being insecure sometimes makes me feel clingy, which in turn, pushes him away. I know that my constant worrying is driving a wall between us and making me miss out on just enjoying his company. Our relationship is great when I'm not crying/freaking out/being overdramatic, but I know I can't keep asking him to put up with my behavior forever.

My feelings about our relationship are just so… fickle. I have moments where I become crazy and anxious about our relationships, and then other times, I recognize that I'm being silly about my insecurities. When I start feeling unstable, I try to focus on my hobbies/passions and to keep busy, but I was hoping for some more insights/stories about similar experiences. 

I also think I'm more emotionally-invested in our relationship, although I think that has less to do with our compatibility and more to do with who we are as people. I think more about my relationships, whether platonic or romantic, than he does about his. Is it normal/okay for there to be an imbalance? He does a lot for me and he treats me very well; I just know that he doesn't care as much about our relationship than I do, and he would definitely feel less affected if we ended our relationship. Is it possible for two people to still work in that case?

Anyway, thanks for taking the time to read the post - I'd appreciate any insights!
