I'm tired of being unpopular. I don't know how long I want to put up with all those craps of being outsider in my life.
I'm sorry that things aren't going your way. You've had some recent disappointments with people.
I can empathize with you. I'm a terrible introvert, and was never "popular." I wasn't
unpopular either--I was a non-entity, and that can be worse.
That being said, popularity is highly overrated. Maybe you feel like an outsider because you're trying to join groups that aren't the right fit for you. If the group isn't your fit, you need to find a group (or individual) that is the right fit. It may take a long time (can be discouraging) but don't give up.
My suggestion will sound trite and overused but it's true. If you focus more on finding activities that you enjoy just for the sake of enjoying the activity by itself, you will probably come across others of like mind. Secondly, turn your focus outward. There are other people who need your friendship. I don't mean taking on some pitiful being as a fix-it project or becoming someone's servant. You don't want to control another person's life or let another person control you. But there are people in this world who can benefit each other and enjoy their time together.
You have much to offer, and there are people out there who will recognize that. Don't give up.
