I get it. I really do. I wasn’t putting in as many miles as you were, but I was somewhat addicted to my training. Something you have to resolve in yourself is long term health. Living the rest of your life in a healthy state is a big deal, and is worth potentially months of habit and diet adjustment. Sounds like you need to find another hobby that will occupy the running part of your mind. Learn an instrument, learn a second language, take some art classes, take up competitive chess… anything. Above all you need to rest and eat the food. Seriously rest, like 10 hours of sleep per 24hour cycle + naps. Eat the food, eat all the food. You don’t have to go fast food and junk food crazy. Just make sure your plate has all the S’s (salt, sugar, saturated fat) and eat till you’re full. Have easy snacks readily available. If you’re hungry, eat. if you’re thirsty, drink. Otherwise, do your new hobby so you’re not obsessing over the fact that you’re not running. When your metrics are good (sleep quality, constipation, body temp, menstruation intensity, blah blah blah) then consider bringing running back into the picture. Keep in mind this process could take months, that’s why it’s important to keep the long term goal of health at the forefront of your mind.
When I finally started running again it was training for a Tough Mudder. I was probably a bit overly cautious when I started, but whatever. I only ran twice a week. I limited myself to twenty minutes per run. My goal was to get faster, not to run farther. So I tracked my distance each run so I could extrapolate average mile time/pace. Over a ten week period my average pace went from 11:30 per mile to just under 9 minutes per mile. As a result I ended up running farther. It ended up being plenty of training for the Tough Mudder. I was able to complete the entire course without getting winded or really slowing down. I wish I had done more pullups, but that’s another matter entirely. I’m not saying you have to do the same thing, but just keep in mind it’s better for your training goals to be faster and stronger as opposed to farther and longer.
Rest, eat all the food, fill your free time with fun and rewarding hobbies. You can run again after some time of healing. Good luck!
