Feeling burnt out after 2 years

I have been at the office for a little over 2 years, and recently I have been getting a lot of cases back with no or little amendments and have to do 2nd NF, only a few allowances in the past couple of months and working on my first appeal. I have been able to make my production at 95 for every quarter but I’m feeling burnt out. When I started this job a lot of people told me the first 3 years (or even 5) are the hardest. Does it get better?
