Not caring enough is a fight. making sure that you do somethign that you do care about might help make the other things that you don't care about have more meaning.

Everything has a point. Might not be apparent but all things have a point.

You are not lazy. Just because it is hard to get things done and sometimes it is to scary to get hurt, that doesn't mean you are lazy.

Getting hurt again is a great reason to not do things. I have used this more times than i can count and I am old so I have done it many many times. However, not doing something because you might get hurt also means that you are restricting your chances to feel happiness and joy. Clinging to the pain makes it impossible to feel joy.

You are feeling lonely and are hurting because you are afraid to get hurt.
If you took a risk and got hurt, would it feel worse than it does now?
What if you did try something, even amidst fear, and found that you didn't get hurt? What would you think if that happened?
