Need some clarity in my life pursuits

I’ve felt unfulfilled in my current job for 5 years now and pursued wellness and then life coaching training because I thought that might be what I want to do but it’s been 4 years since the trainings and I haven’t been able to transition into that business. My job right now pays me a good salary (over 100k), benefits and pension so monetarily I would need to make 250k a year to maintain my current lifestyle. I only made about 5k a year in my coaching business doing it part time and it’s difficult for me to think about leaving my current job without enough financial backing from the new pursuit. At the same time I’m beginning to question whether or not I have what it takes to be an entrepreneur and coach or if I even want to do that – likely fear coming up but it could also be that I pursued coach training as a means to escape my current job. I’m not sure where to go from here and feel very stuck.
I also find it hard to do both because it’s taking away from my family and small children. I’m not sure how to make this transition or if I’m being honest what I’m transitioning into.
