I can totally related! I have felt that way for a long time! My Dad passed away over 4 years ago, and my Mum just can't get over it, so she goes no where and does nothing, and so I am her primary contact, and I have to worry about her all the time. She is also very wrapped up in herself, so even when I needed her the most she wasn't there for me, and it makes it really hard! It would be nice for someone to want to focus on you, and put your needs first! But I guess as we get older that happens less and less!
Take good care of yourself!
