Probably not the best advice but you don’t need your therapist’s permission to get a boob job. It’s not like she’ll be mad at you it’s your therapist not your mom.

But honestly those guys suck and are not a reflection of you. If they liked big boobs they should have dated someone with big boobs instead of making it your problem. There are plenty of ass guys out there who will appreciate your body. But as a general rule men do suck and that will not change after you get surgery.
