It could be that you'd benefit from something more vigorous or frankly stressful. I had a period where I didn't do much besides very leisurely activities - was injured and had to stay in bed, recovered. Not just physically but also had no external demands. My stress tolerance went down and I was hyper all the time, but I started literally playing fps games and high intensity cardio (the kind of where you go hard for a minute or two and have to take a break) to get adrenaline flowing in my body and get used to it again.
