Totally feel your pain, i stupidly decided to give up car for a year and rode 36-56 miles day to and from work, except all i did was ride myself into chronic fatigue and now struggle to ride a bike more than 20 miles and get out of breath climbing stairs, i have to have a “pre-sleep” on the sofa at 8.30pm before then climbing into bed feeling grotty.
Hate looking outside at the weather and not being able to take advantage of it.
Mood wise, i am lucky to live near beautiful coast line, so will bimble on bike to the coast about 12 miles, and bivvy overlooking the beach, does wonders!
