I have just realised to what extent i distance ppl! wat do i do?

Honestly, you've already addressed all the things you do...now stop it. Seriously, think of how you feel and ways that you can show how you really can express yourself towards these people and in other situations. If you catch yourself doing something that seems rude, apologize, say you didn't mean it to come out that way, and then find a way to compliment them. At first, it may seem awkward or robotic, but if you really mean it, it'll become second nature :D
