Writer's Block

 I have been wanting to write more fanfiction, but I just can't bring myself to do it. I get afraid I'll be stuck, I wonder if I'm even writing this for the right reasons, I initially wanted to write it for myself, but feeling like not many people like my work makes me feel discouraged. To be fair it's a niche genre. Still it's depressing. I also feel like the people who are interested have these high expectations, high expectations that I cannot fulfill. I have these great ideas that some people seem to like but I get in my own head, asking myself can I even deliver? I don't know what to do. Should I take a stab at it anyway? I truly love writing fanfiction. I just don't have enough faith in myself I think, and am afraid to show it to anyone I know. I just wish I had people who I wouldn't feel embarrassed to show my work to.
