I've been fantasizing about completely giving up on myself and my life
Why would you fantasize about that?
Because something about giving up makes me feel warm and safe.
It is understandable to just want to get away from everything sometimes. But it is not good to spend your time fantasizing about getting away too much; it is better to think about ways to improve your life instead of constantly wanting to get away.
I agree when you put it that way.
I'm happy you agreed with me. I'm sure you' are capable to face your problems bravely. Running away from them is not a solution.
