Do you think it's bad that I don't like my family?
It sounds bad. Can you tell me why you don't like your family?
They're behavior is really disappointing and I don't want to spend any time with them. They're honestly a bunch of losers.
Thinking your family is a bunch of losers doesn't seem like a very good reason. It's wrong to dislike your family for silly reasons. You'd hate to lose their support if you need it in the future.
I really can't count on them when I need them. They disappoint me all the time.
I think you need to be patient with your family. Not everyone lives up to expectations and you have to accept them as they are. They're your family and you should love them even if they're flawed.
