Regardless of this being a comment about your LGBT+ identity, this is good advice for anyone young.
All you out there 25 or younger, stop fighting who you are. Stop trying to fulfill other people's expectations of who you need to be. Focus on yourself and who you want to be and who you are.
To a degree. If people are telling you "don't pursue that career in art, go get a normal job that at least buys you some sanity in the evenings", then maybe it might help to listen to them a little. You can still pursue art in your free time.
That's advice on what to do, rather than who you are. I agree that it's great to choose a career path that allows for financial security, but you can do that and decide that you're an artist. They don't have to be exclusive of each other.
