Life Sucks and I'm Envious

Life sucks so much. I don't think I should be a nice person considering it hasn't gotten me far in life. It's like everyone who is, seemingly, an evil person has whatever they want/need. I'm stuck in an abusive household with a parent that gets mad over the fact that they've has to parent me my entire life and an abusive, temperamental sibling. I try to remain hopeful and try to work for where I want to be and towards my dreams but life is really kicking my ass. It's very "one step forward, twelve steps back" for me. I do try to tell myself that my life isn't that bad and there are people near and far going through way worse than me at the same time I shouldn't invalidate my feelings and experiences in life. I just wish someone would give me one chance to grant a single wish, I wouldn't mess it up. I'm trying to be optimistic that things will begin to look up for me one day, very soon. It's just hard to keep going and not give up sometimes.
