<human>: Could you distill the essence of the text into 1-3 sentences?

I broke it off with my ex 5 months ago for a multitude of reasons. We met online and were together for 7-8 months in a long distance relationship. She lives in NYC and I live in Ontario, Canada. I spent 2 days and 1 night with her a month into our relationship. 

Anyway's It's been 5 months since break up and I cannot only not seem to get over her, but anything that reminds me of her. Than can be any time of food that she liked, type and brand of clothing, NYC or even certain TV shows. I am hung up on her and our past and our relationship and cannot seem to overcome the sadness and grief associated with her and the things I mentioned above. 

How do I get over the "indicators" of her and the negative and sadness related to them. For example hearing or thinking about NYC makes me panic and tremble. I get a sinking feeling and feel like I never want to go there again. Even though it's an important city to me because I am in the finance/banking industry. 

Here is an in-depth link to my relationship with my ex and the issues and outcome.
