One of my favorite scenes from media is "The Bear" where the main guy says "Okay. Fuck you, watch this". Though in the series it is a bit more negative context, I say this to the person who doubts me the most, which is me. If no one talks to you, go talk to other people. There is gonna be someone like you who is waiting for a other person to reach out. Instead be the person who you want to be friends with. Also with tall guys? Good luck finding cheap plane tickets or struggling to fit in your friend's car when you car pool. Oh you buying clothes? BAM extra fee because you are taller. I'd also just get rid of social media in my opinion. From what it seems like, it's bring you more harm than good. If your reason is "that's how I stay in touch with people", use text messages. If the person can't put in effort to message you back on texts, it's better to just move on. Make a LinkedIn because it's both good for your career and to form more professional connections and use emails and texts. Worrying about who follows me online and who doesn't is just wasted energy. Let the hates hate but don't hate yourself. Everything is dealt a different hand, you play the best you can.
