A lot of people I have talked to have told me to "take my mind" off it, but they don't understand that my mind is literally constantly reminding me, almost tauntingly.

I'm certain that doing Wim Hof method breathing or/and cold showers (or ice baths) on a daily basics, would help you to develop an ability to stay in the moment and gain greater control over your mind. From my experience, I can say that the breathing & the cold exposure has allowed me to gain much more awareness and perspective in life and I also acquired much more resistance against every day stressors, whether their physical or mental. I realize it isn't easy to convince yourself to get started with these practices, as I wasn't able to persuade any of my friends (except for my girlfriend) to get it going :) But I promise you, if you give it a try a couple of times, it'll naturally become something you crave every day!

All the best!
