I have that kind of feeling when I started posting content in the platform and even posted an article asking if this community is also for ordinary people like me but even so I did not stop. I continue to write and submit original content and started to earn few rewards. If you check on my blog, there are only few rewards, that means that since the time I started posting, there was a development, there was a growth.
Its alright to express how you felt because its not easy to create a content and post it and after 24 hours no rewards. I've been there and this is what I'm going to tell you, DON'T GIVE UP, NEVER GIVE UP.
