Help!!

Me and my Boyfriend have been dating for a year now and we are on good terms, however towards the beginning of our relationship him and one of my friends just made me feel insecure about myself and try and belittle me which still hurts.

My boyfriend and I are really good at the moment and he makes me feel so good about myself but my friend has now started to contact me about meeting again and I am scared it’s going to be the same way as before. I try to block out how I feel but the feeling of them hurting me don’t go away. Am I being too sensitive and over paranoid?
