You're not worthless, don't tell yourself that. A large percentage of people in this world don't even know how to read and write. The fact that you know how to do something like that just proves that you're capable of great things. Everyone on this forum should that into consideration.
You're great no matter what. I may be new here, but I can see that you've been on this forum for a long time. The people on here love you. Please understand where I'm coming from.
