I haven’t read anyone calling you delusional. Just that your perceptions and assumptions are not seeming to be based on facts.

You spend lots of time trying to figure out what people were thinking or why they did something, but that’s just not something that can be answered.

Instead, focus on what you can do differently to elicit more positive interactions with people. I mean, the only person we really can control is ourself.

Someone suggested working (or training toward working) doing something that is interesting for you. It’s an idea. Building your own skills and interests will perhaps help you feel more comfortable in your own life and open doors for meeting people who share your interests. Gaining that level of independence should help your confidence too. Those types of changes will gain you that interpersonal respect you are looking for.
