Hey crimsonjunk,
I can relate. When I stopped using drugs and alcohol it was super tough. Things started coming to the surface that I'd held down for years, and I remember at least one time having to recover immensely from a session. I think that sort of pain is ultimately healthy, part of the process of digesting reality.
I think I've come to the sort of road block you're describing. Here's my take:
A lot of the time, when we actually start engaging in therapy, there are more than enough topics to keep us busy for a while. As time goes on, we move from the more imminent and painful topics to finer points of life. It can seem like therapy becomes redundant because as we're so used to having urgent issues put into perspective, once the urgent matters are appropriately dealt with, we almost think that there's no more. We're not used to being faced with anything but the most difficult dilemmas.
But there is more there. It may take effort to unearth these topics that more fine-tune us than replace sections of our psyche, but my intuition is that they exist. It may take a bit of a different approach. I can't quite put it in words.
So I might prompt you by asking, now that you're relatively stable, what your more specialized, but not insignificant, goals are. Maybe you want help with how to better treat your significant other. Perhaps you want to know what you have to do to go to college (if you haven't already gone). Or i could be that you want to gain closure and apologize to people you've wronged in the past, but aren't sure how to approach this.
I would urge you to open up a bit more to your therapist. Draw on the motivation it took for you to face the most difficult topics in the past when you first started seeing them. You're at another level now.
