Hello Marylin
I sometimes have comparable feelings towards my mother as to what you describe... even though she isn't that abusive usually. Maybe it would be best to stay clear of these parts of your family? They probably won't change and it's only wearing you out emotionally to deal with them.
I can relate to your frustration about the hot weather... I' m going to have six weeks of summer holidays soon and I won't be going anywhere.. knowing that people will tell me about their amazing exciting holiday experiences in september...
And I can relate to your feeling of loneliness my only friend I have at the moment will be in Thailand for three weeks so holidays probably won't be very social for me either...
