/ic/ - Artwork/Critique

I want to do comics, but I've never done any sort of fiction writing in my life and I really have no idea how to start.
I think my art is high enough quality that I'd be satisfied with how it looked visually, but I can't think of a story, character personalities, or even fucking names. I don't know if I'm just inexperienced and if this will get better once I start taking real steps, or if I've commited the sin of living too easily or something so now I have nothing to say. Part of me thinks I've had an overall lack of confidence in myself and even my own thoughts for years now. I can't confidently say I really know anything for real, and that makes it difficult for me to think of a message I want to send without thinking "but what if I'm wrong." I unironically live under the whole "the only thing I know is I don't know anything" mindset and I feel like all my thoughts and feelings are something that could easily change.
I'm not even sure if I've really lived too easily, or if I just downplay everything I experience/everyone exaggerates their own. Like literally the last time I had to go to the Emergency Room I confused the fire fighters because I was trying to make what I was experiencing not seem like a big deal. They basically had to fish it out of me that I wanted to go to the hospital, and then I learned if I didn't go that night I would have probably died.
