Hi O_L, I'm looking at the date ... this is the time you need support the most! I think its natural to feel devastated after trying your best and not getting the results you hoped for. I think ultimately the other person is at least 50% responsible to make things work out no matter how hard we beat ourselves up for our won shortcomings. I still don't think D is the way to go for most of the problems here just as murder is not the way to go for someone who may have wronged you. But we can't control others' free will - they will still murder, cheat or file D.
