The thing that i know about my self

the most important thing that i know is that i don't know any thing about my characteristics and it makes me confuse.
these days i try to find something important about my connection to others, but something annoy me  that i dont know what is it. i lost one of my relationship, if i want to go closer i lost one of my close friends and this is something that i dont know what i should do about it.
i hope that i can find the way to solve the problem.
