Oh no. Oh, I am so, so sorry.

I'm glad you can or have to keep up some exercise, it will help you in the long run. Not biking or working out at all would give the sorrow an extra hold over you that it doesn't need. You probably won't get any joy from it for a while, but exercising makes you more stable for the long haul.

After my brother died (heart attack, not suicide, which must be SO much worse) I found a quiet track in the woods where I could ride and cry and scream and cuss without seeing anyone.

We're all thinking of you. Hang in there.
