I've been seeing my T for almost 10 years. I know that's a long time, but I have episodic depression, anxiety, SAD, PTSD, ... so it seems never ending.
You don't say where you are from. If you're in the US, we have finally have mental health parity so the insurance companies cannot limit mental health services.

2 years does not seem long enough. Can your T request an exception for additional therapy?
