I feel the same way and I think constantly about how to improve my next interaction. My efforts are rarely fruitful, and I am mentally exhausted. I don't by any means have a bad life, but I feel like I am always strained. Also as I get older (19) I feel like it will get in my way of making a good first impression with women. I'm not looking for a relationship right now, but I feel like even when I am, no one will want to deal with someone who is essentially an embarrassment timebomb for myself and those around me.
