Hi Abby and Welcome
It is good to see that you know that something just isn't quite right for you.
I think that you should talk to your Doc. again and explian this in further detail, also you shoul take what you have wrote and show hiim, as this can give him a better understanding of how you are/were feeling at that time.
If he shrugs it off get a second opinion, it sounds like you may have depression, or post tramutic stress disorder(Sometime you have repressed memories that you are not aware of), or maybe a personality disorder.
I am only guessing as I have all three, and it sounds so familiar., especially the numb part.
In anycaase you really should not put this off, It is important to understand what is going on for you, It could even be a situational depreeion.
Best of Luck
