Do it! I only got to do 4-H for 2 years but I was so glad I joined! It was so much fun and I learned a lot. My group was great and when we went to county fair everyone there was nothing but nice. There were other people my size and no one gave me a second look. 4-H is about having fun, learning, and making friends! Of course, this was just my experience, every group is different, but I definitely recommend you find a good group and try it. If you don't like it you can always quit, but the cut-off date for signing up is coming up. I say go for it!
