What I meant by ignoring others is when they clearly are not interested in helping you. But I can see we are getting nowhwere fast with this. I am not sure what you want. I am not sure what "really demonstrating it" means. If you want to ignore me, go right ahead. If my advice, based on experience, isn't good enough or clear enough, then I don't know what is.
I used to play the "nobody can help me, nobody can understand me" game a lot when I was younger. I would ask for advice, then when I got it I would turn on the person because it wasn't "appropriate" or "useful". I felt very justified in doing so. Then I would complain that nobody liked me, that nobody wanted to help. It is a very vicious circle and the ONLY way that you can get out of it is to stop focusing on SELF and start thinking of OTHERS. Lest you think, "oh, that's easy to say," let me tell you it took FOUR DECADES for me to get that concept. But once I did, things slowly started turning around. No, things aren't perfect, and I still have problems some times, but I am getting better. But you have to take that first step, which is hard. I suspect that you have the tools already, or at least some of them; the fact that you know how (but not when) to use sarcasm is a step ahead of a lot of people with ASD's who don't have that capability. But it is up to you.
