I may have mentioned this before to you but you are now entering the 6-9 months after trauma period where the crisis adrenaline that had been feeding your brain and motivating you for so long shuts down and depression to some extent or another sets in. Basically it's a little PTSD symptoms.
Guard yourself and try to stay motivated. You're in the best shape of your life, don't let it go.
The internet is 90% complaining and entitlement and I hate it because I deserve better!
