Ironically I remembered that my dad's business collapsed, he became an alcoholc and left a for a woman who had a few bucks when I was 14. But again, this was my network breaking down. My mom took the major brunt of this until I couldnt stand her despair and fixed her up with someone who later cut me out (I needed my mom because she was the only one in the family who had had and hence understood depression)and finally came close to doing me serious harm (not physically).
I am a loner too, but not to this degree. Those of you who like to be alone, who can jump in in emergencies? I am having two big surgeries this year, and trying to plan for approaching old age, and it's not smart to have no backup. I usually have one really close friend, but two of those have proved untrustworthy lately. I think it's really, really important to have a network for backup if not for company. Hugs, everyone. Things will improve.
