It sounds to me like you need a break. I would take at least a week off from RP entirely—No thinking about it, no discussing it, nothing—and see if when you come back you have a bit more clarity about what will be the best decision for you.

I will say that at TR, you play two characters you've had for quite some time. If you think you still want to RP in general but find yourself hitting a wall, it could be that things are going a bit stagnant for you. Everyone is different, but generally when people start to struggle like this, that's what it means. Dropping and/or apping someone new might be what you need to revitalize your interest.
