Is it normal that i lost hope in humanity?

I've been questioning myself for a long time about my feelings towards people and their obnoxious attitudes.
I want to be an comic artist and for this there's the need of practicing and receiving constructive critics or tips to help during the progress of learning, but recenly I've noticed that people have become more rigorous about the content of the project. Most of the critics where never satisfied with the results, even if I followed every single step they said.

Even if you do something that is correct, people will brag about, always finding a reason to point out a nonexistent mistake.
What happened to humanity to reach a point where everything needs to be questioned?

Not only about my work, but the entire world is distorted (sort of).
I've been trying to avoid disappointment by entering in a state of despersonalization. This happened a few times and, I must say, life looks like a a theater when you manage to achieve this state. I feel like my actions won't matter anymore because at the end, everything is going to be erased and went black. I want to put a little bit of chaos in my mundane life like, I'm not a pretty person, in fact I'm ugly, but I want to have a relationship, So I thought of being the one who takes the action and go after my loved one (even if it's not the most perfect, I want to find the one who matches with me). I want to travel and live in another countries, with no knowledge of the local language, no money and generally confuse and lost.

Should I be worried about the world or not? Do I really need to follow orders and fail miserably at the end? If so, who cares about my work and it's quality? Who cares if I'm a weird person?
Really, who gives a shit?
