LMo, has a good point, once I thought a friend of mine put me on "ignore", but it wasn't meant, personally for me, it was "ignore", or technically, "not recieving PM's", so I wouldn't feel they or the person you think is singling you out as "ignore". People, sometimes just need their space, and that is fine, their is no need to feel anyone is "ignoring" someone.
It's good you can come here and talk with everyone, from my own experience, the majority of members are good listeners and understanding, helping to support another person, or listen. I feel for you, and understand some things you are talking about, my personal view is that much of this takes time,living,experience,self-discipline,self-esteem,growing, maturity wise. We all seek attention, from childhood to adulthood, some seek a lot and some need very little. I think it is something that we use to assure ourselves someone cares ? I don't know the right words, but I think I know what you are driving at. Let me re-assure you, there are many people that do "care", "understand", and relate to what you are going through, and we all feel for you.
You need to learn patience and/or understand, that when you are talking with someone or asking something of them or from them, that they can't just drop everything and run, people, just like you, have many things going on in their worlds, many much more severe and serious than your own stuff. If someone doesn't get back to you, doesn't have to do with you, doesn't mean they are ignoring you or annoyed with you, so do not feel that people are ignoring you.
Many people DO care about you.
