I think that when you have hope,even a small amount you should give yourself a chance.you can always change your mind if things get worse.you are so lucky to have that glimmer of hope -keep hold of it.you will never know if anything will change unless you hang around to find out.I am sorry if I sound like some type of pro lifer as I am not but do believe you have to be 100% sure this is what you want as there's no going back.i wish you peace and happiness in whatever decision you choose my friend x
