Help for possible PTSD??

So lately Ive been have really bad triggers, and Im starting to think I might have PTSD. I always thought you can have triggers without the full blown disorder, but maybe I was misinformed. I received free counseling from my college, which ended about 8 months ago, and i liked where we left things off. Im a lot better since then, but i still have really bad spells where Im reminded of my traumatic event. I was wondering what a therapist could actually do to help me, before I spend the money. Thanks
