It feels as if I'm not enough...

I feel so tired of everything right now. It feels like I won't ever be genuinely happy and that I would only express through what I did over the years. I'm a nice person, but when I am not interested in something and people show it to me in my face like I'm interested in it, or assume that I'm going to be interested in it, I just turn my attention towards them and nicely sit and watch because I didn't want to be rude. I didn't want to act so aloof... but maybe that, me acting aloof, is for the best. Maybe I can show more honesty and genuineness by actually showing what I truely feel, rather than just being nice...
My family doesn't deserve me... All of that love put to waste. I have wasted my love on people who doesn't have common knowledge.
