I'm very thankful of my friend even though sometimes I don't know if she still wants to be my friend but she still helps me in ways she's not there for me all the time like she used to be but I'm very thankful that she does help me out when I really need her. I just wish i could do more for her.
Someday when your strong enough you will do more for her, give yourself a break for now. Thanks for your post.
