Don't let that stop you! Practice can make you better. It may take a long time, or maybe you will not reach the point you would like, but you would get better than you currently are, and you could express some things through drawings that you can't through words.
It's true that I'm sure you can express different things by drawing than by writing or making other things but I'm really terrible in drawing and don't really have time to try to improve ! But maybe one day... But anyway thanks for your text ! (and for all your "pictures" ! )
