Dude, you are unwell. You need some homies in real life to clown on you and bust your balls a bit. Grow some thick skin and don't take shit so personally. Also, don't post any more poser pics, you definitely did not land those kickflips on IG.
You are inviting people into your world when you post yourself online. If you don't like the feedback, then quit posting or change your tune.
If everyone around you seems like an asshole, you may need to ask yourself, "Am I the asshole?"
