I don't know if you realize it, but you aren't the only one who doesn't think they want to go back to their world after this. We have all changed and some of us have nothing to go back to on our worlds even if things are restored. We are fighting for more than just restoration then. We want a way to go to a different world or to stay here.

Just because time is short and you don't want to go home, doesn't give you reason to give up. Just adjust your goals and keep pushing forward. There is always a long term unless you give up.
