I don’t understand

Feel that!! I guarantee your not being annoying though. As I get older I realize I put more effort in people than they give me. So maybe put in the same effort I’m not sure if that’s good advice but maybe something that can help you. Also something that’s been helping very much recently is “don’t chase,attract.” let people come to you. That will show you who’s truly there for you.

I think many of us and I've said this before are Hyper Sensitive individuals that take any relationship whether that be friendship, family, dating, etc. to heart. We value these relationships greatly and if they are broken its heartbreaking. I used to view my friends as "brothers" and as I've grown older and they've started their lives with kids and wives, I rarely hear from them and it's still even at an older age heartbreaking for me. However, I'm pretty confident they don't feel the same otherwise they'd reach out. It's not to say that it's deliberate but it still hurts.

I second what the person above said. I used to get so bothered by friends and family not responding at times. It really comes down to who cares enough but also worrying about taking care of you and loving yourself or figuring out how to. Because ultimately, we're with ourselves 100% of the time. If that makes any sense.
