Hey Excillon, the best remedy is to take a break from doing models at all, I took along one before I started working on Models of any kind, since its been a while ( year or so) I enjoy making them again, Macross & Navy Aircraft kits. but if your trying too coax or mentally trick yourself into making them, you still won't enjoy it as much, basically its burn out from model making, we've all been there one way or another.... glue & putty and smudges oh my!!
Take a break my friend, the passion will return, it always does!!
