Personally, I think healing is a process in which you really don't have to try so hard to realize the things you ain't comfortable doing. Go on spending a month or two hating your life and hating others. Go on curling into a ball and crying and wishing you didn't exist. That phase shall pass, and even if it won't pass, remember this: You will be just fine knowing that there are millions of people out there not loving their lives but still keeping on living anyway. Btw, your future might do wonders, who knows? The point is: all of your feelings are valid, you have the right to feel whatever in this world, just please don't give up on life right now.
