I'm working on trying to not be driven by guilt as well. It's not as easy as it sounds. I hope to read more about your experiences with it.
No, it is not. When guilt is so close to you that you start using it as a reason to do things, it's very, very hard to do something else - something better, in this case. I'm afraid I'm not going to be of much help to you, for I don't have much to say - and I suspect I won't, either. My progress is mostly intuitive, hard to put into words. I can show you the islands of wisdom between which I've travelled to get to where I am, but it may be the best I can do. However, I will probably write something about it at some point. I'll keep in mind that I could help a fellow human by describing the mind processes with precise detailing. For now, I'll say this: Stay strong. You got this. Carry on no matter what.It's not as easy as it sounds.
