I find myself kind of a mix.
Sometimes the exhaustion of just carrying through on a commitment I wasn't totally into leaves me wanting to pull out / disappear / not show. And other times I wonder if it's a good use of my time and whether a different opportunity is better.
I'm pretty responsible, though. If my presence is necessary, I show anyway. I only flake if I assess things and I'm inconsequential or plans can be changed easily, but I usually still feel bad. What happens now is that I just never commit in the first place. But I don't like backing out of things after I have agreed to them; it can be a trap for me sometimes, that sense of responsibility.
I definitely have a war going on between my thought process (which spits out answers, i.e., closure) and then feel kind of hemmed in / smothered if I don't have enough flexibility there. I realized over the course of my life that I need more space / leash in order to be happy.
