I just want to walk away from everything and everybody.

I did for somethings. Be careful what you let go of. Especially if its people. Yes it is good to let go of things that hold you down. But first really ask your self why this weighs you down. Why does this effect me this way. and can i change it without any losses. Reduce your chances of regret. That also holds you down. Then you have something to let go of again.
