If u don't mind me asking, why are u unwanted in the first place? If u feel like your being ignored, make an effort to make yourself visible. Do things that people would be amazed by. If it's a really bad situation maybe find some new vrienden of hang out with people who will accept u and make u feel important.
Simply put, u need to put effort into changing that feeling/view on yourself.
No one just simply feels happiness and acceptance door doing nothing and just expecting these things to come along. That'd be far too easy. u need to just go out there with a positive outlook and change it for yourself. No one is going to change it for you.
It may be blunt, but I've dealt with this with others and myself. It's the only way, u just need to take action. How do u stop feeling unwanted? Take action, don't sit around pondering, and just go and change that feeling, there's no easy way out.
I wish I had that answer as well. I severe depression. Alot of people are joking on here with their antwoorden and Its not funny if u go through what I and many people go through. It hurts so bad when a person feels unwanted, and lost and alone. That is pretty much how I feel all the time cause of my Severe Depression and Anxiety Disorder. Like I said, I wish I had the answer too, I hope we both find the answer that will make us feel better.
