study hours/schedule?

what are we averaging folks? I feel like I am overdoing it going from 7 am - 9 pm. I've been studying since end of Nov but ramped up my hours in the last two weeks. I'm taking solid breaks and took a day off over the weekend. I feel like I'm maybe going overboard but have a massive fear of failure that always makes me prepare excessively. Would love to hear what others are doing and maybe force myself to balance a bit. I miss seeing my kids :(
