Family Issues Support Group
Family issues is a huge range that go from minor conflict to major misbehaviour and even abuse on the part of individual members of the family occur. Whether you feel you are in a dysfunctional family or you're dealing with a very specific issue, this is the place to talk about it and find others who might be going through the same thing.
As for all of the relationships and babies in your family, that is a real mess. Your family probably qualifies as a dysfunctional family with no one having true respect for the others. There is no way that I would ever date anyone my sister had dated or vise versa. These women must be mad.
You are right - just stay away from everyone involved and live your own life. Start by finding new friends.
Good luck!
