Why does my mom ignore me sooo much?

Well, although this is traumatic for you, you ARE, over reacting. It is not the end of the world, and Im sure that mom is not 'ignoring' you. Perhaps when you asked her, she had 1000 other things on her mind, and signing on to the computer was low on her list, as you did say that she was getting ready for work at the time. children are famous for asking their parents to do things for them at the worst possible moments. When you ask your mom to do something for you, and you think that she is ignoring you, stop and evaluate the situation...what is going on...what is mom doing. then, you can ask her at that point if she forgot or whatever.
