Why not go back to running? I think the whole chronic cardio thing is a total misunderstanding for most people. It's chronic cardio when you do it at a high intensity. It's healthy slow movement when you do it at a lower intensity. At a high intensity it causes stress. At a low intensity it can help with stress. Dial it back from 11 down to 3 and you will probably enjoy it more and it might help.
