Do you feel guilty only for yourself or for your family/friends or others? It's really not that easy. Not that I want to to stop you - it's your own decision at any time - but I think you should try harder especially if you have support and the abilities to do so. I think, it could also be some kind of SI (that feeling of being guilty). I always say the it's easier to overcome SI when the pain of living becomes greater than the pain/fear of death.
