If あなた don't mind me asking, why are あなた unwanted in the first place? If あなた 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 フレンズ または hang out with people who will accept あなた and make あなた feel important.
Simply put, あなた need to put effort into changing that feeling/view on yourself.
No one just simply feels happiness and acceptance によって doing nothing and just expecting these things to come along. That'd be far too easy. あなた 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, あなた just need to take action. How do あなた 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 回答 and Its not funny if あなた go through what I and many people go through. It hurts so bad when a person feels unwanted, and ロスト 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.
