Talk to an accountant or CPA before you go ahead and sell with the idea that you don't get hit with a capital gains tax. Nothing worse than getting audited or hit with an unforeseen tax bill.
It sounds like you are house hacking well though. You aren't living for free, but your living expenses have been severely decreased. That's the goal of house hacking. Don't beat yourself up about the situation. Besides, you did what a lot of people don't do: get started. Give yourself a pat on the back for that one.
Before you consider jumping in with both feet on a sale, consider what you would do when you sell. What's your goal of selling? It sounds like it's to run from an imperfect house hack. I think figuring out where you want to go and creating a pathway to get there is really undervalued. As a newbie, I think it is very easy to get focussed on the systems of these sage investors because more often than not they can manage the volume as a result of their systems. Before you can create a system though, you need to know how to operate the system before you can handle volume in any capacity. Getting one call about a toilet is a lot better than getting 100 calls about toilets especially when you don't have a plumber (or aka team).
I think the real beauty of real estate is that everyone follows their own path. To me this means that there is a system of checks and balances that presents itself in your bank account. Is your current arrangement perfect? No, but learn what you're good at and figure out how you can capitalize on your skill set. In the meantime, if you're not happy in your current arrangement because you think you could be profiting more, find a property where you could achieve that and approach the seller with a subject to offer. Subject to referring to you selling your current residence. You're comfortable, but you want to be more comfortable. Don't put yourself in a stressful position and go shopping for a new house until you find something that you think could work.
Sorry for a long winded response, but hopefully it helps.
