>>8343I've honestly felt that way myself many times, and I've realized that we all simply have a select niche that we would fit you. I'm sorry your friends don't make the effort to include you, but in my eyes, you shouldn't beat yourself up over it or try to change yourself to fit in with them.
Instead, I feel its more important to accept the person you are, flaws and all, and be confident in that person. Be confident in your interests and hobbies or mannerisms, no matter how "weird" or "niche" you might imagine them to be, and look for like minded people.
Interact with communities of your favorite games or animes, go to conventions and compliment someone's costume and spark up a convo about the series their dressed up as, compliment someone's cool t shirt you recognize, etc. Every little effort counts and builds to a greater whole.
You got this, even if it doesn't seem that way. You'll find the people you want and deserve.
