<human>: I was humiliatingly left for my best friend by my ex. This happened 6 years ago, so it's been quite enough time to get over it. 

Me (23), him (29) and her (25), now all 7 years older. 

They are still together. I'm in another great relationship. I'm not in contact with either. I am happy to live my life without thinking about either of them, however we run in the same work (and sometimes social) circles and their names pop up. 

I have not had the misfortune to bump into them, but whenever I hear about them from other people, I get knots in my stomach and it completely ruins my day- to the point that I cancel social functions and mope around because I'm so badly affected. 

I do not have feelings for him any longer, and I also objectively see that they are a better fit and that him and I would not have worked out in the long run. We were only together for a year. I am mature enough to see that he was not a good influence in my life although he treated me well. 

However, you would think that 6 years is quite enough time to get over someone. I don't have time to see a counselor, and I travel too much to stick to one. I'm looking for any sort of online resources to deal with these debilitating feelings. 

Sorry if this is in the wrong subreddit, if it has to be flagged/removed, could someone send me a message to direct me to a better subreddit. Thanks.

Can you condense the text into a few key points?
