I am so sorry you are going through all that family drama. I understand completely. My husband and I eloped because of his crazy family. His grandma Mary was not invited because she's a controlling psycho-path and she had a huge tantrum because she wasn't invited and she called everyone in the family and told them lies about us. So we eloped, didn't even have a ceremony. My friend is an ordained minister and she just signed our wedding license for us and turned it in.
I don't have any wedding pictures and we never had a reception because of the family stuff. I don't regret it or feel bad about it. It was very simple just the way we wanted it, "sign here. Okay you're done."
I think you should just go to your brother's ceremony and skip the reception. I also think you should stay away from the crazies in your family and do get some counseling. If you're depressed all the time that is definitely not normal and you could benefit from talking to a professional about it. The professional may be able to prescribe something to help you feel better.
