Well, I've also tried to forge bonds with other creators on Discord and other places, but when there isn't anyone with similar interests and passions as you, it's only natural to feel isolated. It's even worse when you see other people finding friendships over common interests that you wish you could have.
It's tough. But once you find the one person who takes a chance on you and your projects, then they can help you find the motivation you need to keep creating comics and give you pointers on how to do better. That's what I like to believe, so just hang in there you know.
