I can relate to you 100%.
I got into the platform and spent almost a month just looking and lurking and reading other people's posts, but had no idea what to post myself. I've actually just posted two things myself in the span of a month and a half. It's a bit of a struggle at the start but I bet if you let go and start posting about you, and what makes you happy, you'll get there.
Looking forward to reading more :)
