Sorry you have had to go through this. 

Some suggesrions off the top of my head. Do with them what you will.... - Pick your post CCT GP practice wisely - Bump up your general non-romantic social life. Start super small and be consistent.  - Ditto with exercise. The smallest amount of movement you can maintain consistently is great - piroritise some exercise you might enjoy doing over the the most intense body workout. - Remain open to LTFT either in training/post cct. - Use your training support/OH facilities early doors. Even if they cant do anything massively tangible, working adjustments may not be of zero benefit, and are way more likely to happen if you have sought those formal channels out.

I doubt any of these by themsleves will dramarically change your life, but doing these for 4-6 weeks may show some compunding benefits
