This not trying is getting me nowhere except making me feel guilty that I bought an expensive bike that I don’t use anymore.
Hey, there are lot more important things to feel guilty about than THAT! Have you stolen from your elderly grandmother or killed puppies or something? Feel guilty about things that are actually wrong, okay? Don't waste precious energy feeling guilty about something so trivial as a bike not being ridden. Most bikes are parked more than they're ridden, anyway!

Words that helped me, and transformed my way of thinking, uttered by a friend who knows how to pierce right to the center of a thing: Regret is poison.

If you are living with regrets, make sure it is about something you should actually be regretting--then go make it right, if you can. If you can't, learn your lesson and let it go. You cannot change it. You're not alone in that position. We find a way to go on in spite of it. You will, too.

I'm glad you're getting help. You're bike is just on the shelf for a while. It's okay.
