I'm glad that you all can relate to me. It makes me feel better that I'm not alone in this. But it really sucks that we have to go through this. I'm sorry to hear about your situations.
Yes it's really hard for me to believe that there are more good people out there just because the negative people just get to me so much.
I definitely know people are human beings who are bound to go through shts in this world. And I try my best to try to do something about it. Like for example, even when my dad can't see me as his son because I'm not up to his standard, I get worried when he gets sick out of stress. My little brother can't even stand me, but I still manage to help him with his studies, talk to him to not make him feel lonely and such. But it feels like, I'm the only one trying. Only I'm the one who, despite all the hate that they put through, would care for them, try to understand them. No one ever does that to me and it is what trigger me sometime to start being unkind to people.

Now I'm just wondering how am I gonna get out of this messed up life and find my happiness, find my freedom...

This is so me. And I'm sorry to hear about your brother. Made me think of the time when I tried to take my life in front of my dad, he thought I was trying to put him in jail or get him into trouble purposely. My uncle found me and then rushed me to the hospital. He still never changed, still thinks I'm a disappointment. You are doing good by teaching your daughters the right thing. They should not go through the same things we are going through.
