Clearly you need to broaden you support system. Do you have anyone currently that could step in to help? I'm not familiar with your specifics but would a support group help for the emotional aspects you need? How much of your need is finance based? Do you have any interest in your father' business?

You have friends. Same here. I have found PC is often supportive and there are some amazing people here. Also perhaps you could make more effort to try to meet people who live near you; a hobby group? We have a singles group here that I go to once in while for dinner and a movie and similar. I haven't found romance there but that isn't my goal - I simply enjoy conversation with other adults and getting out of the house because I tend to be a hermit.

Best of luck. Perhaps buy your mom a card or some flowers as a thank you for all the support she has given you throughout your life. You only get one mom in life and it sounds like yours care deeply about your welfare.
