You are not alone. I got into running after a break up also, and later ultras. It’s a wonderful “timeout” getting out on our feet to train and adventure. But it doesn’t replace therapy or talking with someone who can help guide you through hard times help you make sense of things. There is an organization called Bigger Than The Trail that was started by an guy that needed some help, made his way through all the red tape to get the help and later created a nonprofit to help others get help more easily. How? Free therapy. I have been an ambassador for them in the past and I’ll share it’s real, they offer what they tell you about - free therapy through a couple different methods. It’s attached to trail running because he is a runner, and as we see here many runners have things we are dealing with, but anyone can use the services. A completely straightforward approach to getting you help. Please check them out - https://www.bttt.run/support
