Hang on beachguy, it will get better. I am glad you know that there is only one way out, and that is through!
I have had several all day down days, and drinking would get m through it. But I wouldn't be getting out of this at all. i would be prolonging or putting off what I know I have to do, and that is get through it.
for me, I have found just going to the grocery and buying a single item helps sometimes. not because of the purchase, but usually someone smiles at me, or speaks to me and I have to pull myself out of my mental isolation to respond, and once I am out I am good for awhile. Sometimes it doesn't work and I have to just try to ignore it until it goes away.
Best of luck man, good on you for making it this far. It shows me you can do it, because you have been doing it. I promise, we will get through this.
