I'm sorry you're feeling down. I know how easy it is to start accumulating the negatives when there seems like there are more of them than positives. Way more. Being sober doesn't create an instant state of happiness and you know that. But it does help to be able to focus and what you need to change.
I have a ho-hum job at an age I thought I should be doing 'more'. No close family and very few friends. It's easy to get 'sucked in' to feeling down.
Take care - you will feel better, just maybe not right now.
