You play well and have a lovely voice. I don't know what you need to worry about.
Hang in there and keep plugging away (see what I did there?)
Aside...I just broke a string on my acoustic the other night. First string break after having it for just over two years. I put a new set that I happened to have handy and the sound was amazing. Nothing like putting on a new set of strings. They sounded so much brighter than the old ones. I love playing, even if I am not the greatest, but it is so much fun.
Lucky you, you get to share all your wonderful talent with an audience. You'll do fine.
