I feel you . I have a niece with mental disorders and she ' s now a technical adult age 21 with the mental maturity of a 4 year old . I can ' t tell you how thankful I am that I don ' t have to take responsibility for her very often I was born 2 years before her but my poor sister and my mom have to constantly tend to her . She now lives in a group home state ordered but her mom ' s life is permanently damaged . She ' ll never get that time back and she is constantly worrying about her daughter , having to calltext her daughter all the time . And my mom is now her legal guardian and has taken over her paperwork , her legal decisions , etc . It eats a lot of their lives . And I ' m so sorry for them . My sister never had the chance to maintain any romantic relationships because of her daughter . The men she met would run off soon after realizing that her daughter was a permanent fixture in her life . It ' s horrible for her .
