<human>: Give me the gist of the text in a nutshell

Been with my GF for a few months and we've had an amazing time up and up until now. I found out the other day that she's had quite a promiscuous past to say the least. It's made me feel so insecure for all sorts of reasons and made me extremely anxious, scared, petrified and barely unable to function. took Xanax to calm down today as I needed to come to work.

There's no logical reason why I should be feeling like this. I'm with her and she loves me dearly but I'm driving her away but acting so insecure and needy. I hate it so much.

So simple answers to simple question - what can I do when I"m with her and feeling horrible insecure? Talking to her about my issues is clearly not the answer.

Any advice would be much appreciated as I'm really not sure where to turn to here.
<bot>: Girlfriend has promiscuous past. I feel insecure whenever I'm with her so runiing relationship. What I can do do when I'm with her to not be so needy and or insecure?
