As i get older, i'm more likely to project my momentary pain as if life wil bthis pain from now on. So that's exactly what we're talking about. Your mind is going to project this present circumstance into the future. I'll be alone forever. News flash, you can't see the future. No one can. That future projection is actually coming from an emotion. It's not coming from a logical place. Practically, there are practices that can teach your mind to live in the present and train yourself to be in the present. meditation will help with that.
