Despite, everyone else has offered wise advice. Please do not be bullied by your mother or your brothers. I have an adult autistic son who has had terrible depression and suicidal thoughts at points in his life yet my second husband demanded I leave him and his siblings behind and move to the other side of the world 'to make him happy' my youngest was still under 20. As they weren't his children he thought he was most important but he never showed his true colours prior to marriage. Then my parents started the constant 'what about us' the emotional blackmail, my dad would rant at me about what my 'duty' was to them - because I was the daughter! They even started to demand I abandon my children (just as husband 2 had done - I told him to leave if going overseas would make him happy, and he did) parents wanted me to live in with them, give up my job which I loved, not go out with friends etc and be 24/7 carer, housekeeper, mug, butt of my mother's bitching. No room for my children. They insisted I owed it to them! My dad kept phoning me at work to nag. I already did their shopping and visited after work, then walk home (no car). Our family GP, a lovely man, actually told me he felt sorry for me and said I'd not to give in. I knew I'd end up breaking down if I did. Nothing I did was ever enough, they were ashamed of me for having two failed marriages etc. It's not exactly like your situation but I have an understanding of where you are, the guilt, the pressure. And I can now say, with hindsight, do not go there, treasure your life, your friends where you are. She has made her choices & you should not suffer for them, she is not alone either. You are very vunerable right now, use some of the travelling money to pay for counselling instead. It certainly saved my sanity. And yes you may feel guilty from time to time, it's sometimes bred into us, but it's how you handle it and please, always, be kind to yourself.
