If this is the way you treat people and their thoughts in real life, no wonder.
Instead of criticizing responses from people who are taking the time to engage with you, could you consider asking questions? For example, if you feel you're being judged arrogant, ask if that's true.
Ask if people find you arrogant and what leads them to that thought?
The way I see it (as a parent of young DYS adults), the something you are looking for may not be found at this time in your life, and as a probably complex person, may require a lot of hard personal work on understanding yourself.
You've shown an interest in doing the work by coming here. That's a great start. One kind of therapy we've found successful over here is Acceptance and Commitment Therapy (ACT). "The Happiness Trap" is an associated book.
People have been willing to engage with you and try to assist, and I urge you to not look for reasons to dismiss, but reasons to fully understand what has been said to you. Really, life can be that hard.
