I state this too so many people. Why I've choose to remain people out of my life. When you have done everything you can too help others , and they can't be there for just simple emotional support system.
Some of my genetic family, I wouldn't even call family. I'm thankful for my best friends from school, work, etc. Those are people who I consider family. I'll be forever grateful to be able to talk to my "family" about anything, at anytime.
