Hey, go for it! You've already posted enough of a reason to see a therapist. You don't need to have any particular diagnosis -- therapists can be helpful at transitional points in your life or any time you feel a need for change. I wish I'd gone sooner than I had! If you find it isn't worthwhile you certainly don't have to go back. But many folks -- me included -- will tell you it's the best thing we've done for ourselves!
