The best advice I can give to anyone going through a rough patch is to never be afraid to ask for help.
I think sometimes when people start doing improv there's some regression towards trying to replicate the "good" improvisers that they've read about in their improv books or heard about from their teachers. That's understandable, because they're trying to learn technique and stuff, but I actually think that my favorite performers are ones who have unique improv technique but also have a unique point of view that you can feel with them and their performances.
