I feel like I'm not enough for anyone + I'm over-apologetic.

I (20M) sometimes feel like I'm not enough for anyone, but I do have traits that I get myself credit for. I tend to be considerate as much as I can, but even that doesn't stop me from thinking that I'm not enough for the person I'm considerate towards. I also do my absolute best to not overstep any boundaries, but I always assume that I do to the point where I start panicking and apologize more than I have to.

I really do want people to see that I'm genuine and mean no harm, but I believe that over-apologetic behavior is the reason why I push people away unintentionally, and I really want to work on that, I truly do. But I don't want people to think I'm a selfish and careless person.
