I'm not sure what kind of response this reply will get; because I believe you and I'm not going to tell you it's all in your head etc.
Try a visualisation to strengthen your psychic defences:
Wherever you are, even as you're walking down the street. Imagine an egg shaped aura of golden light surrounding you head to toe, front and back. This aura is made from your own positive energy, which you obviously have a lot of as the dark feeds off the light.
Just imagine yourself in your golden egg, shrugging off any negativity with love and happiness.
It takes a while to get the hang of but if you practice it enough it really does work.
Try carrying a favourite crystal with you that you can hold as a comfort too.
I'm sorry you had to go through this and I'm sending you positive and healing vibes xx
