I feel like I am friends with people that do not care of me. And yet I do nothing about them.
If you truly feel that way ask them. If it is how you perceive it, find new friends that will like you for yourself. Don't change to please others, I've been there.
same way there's people who treat you badly and don't care about there WILL be people who care about you. Clear your intentions and always be a good person no matter what and time will do it's wonders, like it always does
