I think you need to figure out a healthy line on what you want to do with your art.
If it is just a hobby, dont put too much pressure on yourself or you will ruin the fun of it.
If you wanna do it seriously, figure how you can improve at making comics.
Ask yourself why you are doing comics. What do you like of it? Do you enjoy the proccess of making your story or you are only interested in the end result?.
If you are not comfortable sharing your stories but still enjoy making them, make them for yourself. I did that a lot when i was younger. Some cases i shared some of the stories with family and friends, but had some ideas that were only for myself.
Whatever is your answer, wish you the best on your path.
