With a post like this, I'm leaning more towards leaving. You are obviously unhappy here and we have computers to talk about here, rather than maintain a certain level of attention strictly for you.
If you really wanted to leave, you wouldn't worry about deleting your account... You would just leave. This post seems like some ploy for attention through a last noble cry for help. To be honest, I was attempted to delete this post because it is quite unecessary, but I figured I'd give you the benefit of the doubt and you can discuss your problems in this thread for others to consider.
I'm not sure I understand why you would want to leave or feel bad though? We should definitely discuss this, because regardless of whether you are going to leave or not - I would not think there is a reason to be upset over any of this. I could be missing things and reading this wrong, who knows. If you are upset, I would definitely like to see you walk out of here with a smile on your face if at all possible.
