Actually you sound highly likeable, and it is interesting that you feel a great need to be liked but you believe you act in ways that make it harder for people to like you.

I would not be surprised if actually people do like you but get a bit exasperated because you are more 'full-on' than most, and you interpret this as rejection and dislike.

Anyway, whether I am right or wrong, you seem to be an unusual person and it may take a while to find your niche. Good luck!
