So sorry you are struggling man. As you said, brighter days are ahead, it just [censored] waiting for them.
I have no advice other than to allow yourself the time to process things. I remember it well when I was going through this with my ex-wife (not my most recent ex). Everything felt so unsettled and I really burnt myself out worrying all the time. And that feeling followed me like a dark cloud.
On a positive note - looking back, I'm grateful for those times when I couldn't see the light. Those were the times that really helped me grow the most as a person. It was during those times I finally learned that I could handle life's curve-balls, that while it wasn't what I wanted, I was going to be ok and be stronger as a result.
I'm really looking forward to seeing your big comeback, stronger and wiser than ever.
