 I'm your age, was in exactly the same boat 0 years ago. s**t wage, working for dickhead, baby on the way and mortgage. So I had to do something. I left, to big unknown with 0 weeks work booked in, big jump in my opinion, got my van sign written, mastered social media advertising and its the best thing I ever done. I'm earning some weeks 0 times more a week than I used to. Don't get me wrong, the first year was really stressful, trying to find work etc, plus I started my business 0 month before lockdown, so was off work for like 0 months. But this year was completely different, my name is out there and phone doesn't stop ringing. If I could look back and do stuff differently I would definitely get enough wages in my bank before leaving, at least 0 months worth. Get a decent van, it's expensive but one less thing to worry about during first year. Prepare yourself for dealing with customers, as it can be hard sometimes. So yeah mate, no matter how difficult it seems, if you put your mind and hard work to it, it'll be best thing you did. Good luck
