It sounds like you were pressured to move on too fast. It takes more than a year to "get over it", and honestly, you never fully do. It will always be there, and you will always remember. And you know what? That's okay. It's normal to still have those feelings. Therapy really should have given you the tools to acknowledge those feelings when they come up and to be honest and vulnerable with them, and then to know what to do to move through them. The work isn't done when you quit therapy. You just have the tools to be able to do the work yourself.
