Hey, happycheeks!
Many of us in here DO care about you very much ~ I know that I do!
In my defense, I don't own a computer & have to use the library's computer. That makes my allowed amount of time in here quite brief, unfortunately. The days that I have my girls, I can't use the library computer since they're young and dependent upon me.
That said, I am sorry. Sorry that you are feeling as though people aren't showing you the love and care that you need. {It is great that your brother and others in your physical world have been there for you to talk to though!} Psych Central is very big, like Queen of Chaos mentioned. It can be challenging to get through to individually help all those who we could. It takes time and determination. Try not to take it personally. I think that you are a very sweet girl ~ and I'd hate to see you leave, because you're feeling uncared about.
Gentle hugs to you ~ and very best wishes!
