I had a similar loss of interest around that many jumps. I think it's pretty common to have a "100 jump slump". I just couldn't get excited about going to the DZ and doing more belly jumps, and didn't have the mental fortitude to suggest trying other things. I ended up taking about 3 or 4 months off. I had to do some review and make a jump with a coach to get recurrent but didn't have any major safety concerns. As others have said, if you're not feeling like jumping don't jump. If you want to get back into it next season, you may have to do some review and a coach jump but that isn't a deal.
