it's a slow process and something that you cannot rush. Thing is to work on focusing on yourself, good things in your life even when it doesn't seem like there's much, work on it. I have been through being left by a spouse and for me it was a full year to feel ok-ish and longer to find my footing and independence. although it was very painful I can say without question that it does pass eventually and there can be good things ahead but you gotta believe in that and claim it for yourself.
