The beauty of this community is that nobody is going to judge you if you are describing your loneliness and your sadness. Better to vent them here, than keeping everything inside as this will hurt you more than anything. I know that I'm a bit head of you, and I'd say that now out of a week: 50% is bad days and 50% good days. I'm not there yet, although I can see it getting better. You'll get there but you need to overcome the shock of all this, then little by little you'll change and see thing differently.
