I went through a rough patch several years ago. My best friend at the time died of a drug overdose that was almost a suicide (he was trying to wreck himself) and my father's heart stopped, incurring massive brain damage, all in the same week.
I ended up closing my business, liquidating everything, trying to help my family until I could see the bottom of my bank account.
I spent the next couple years going through the motions of working hard, but I was lost. I didn't really know what to do with myself, what direction to strike out in. I felt alone (not lonely, but just alone), uninspired, drifting through each day, usually without any sort of momentum or progress towards anything.
I felt powerless to help the people I cared about. And that sense of impotence as a son really undermined any sense of worth I felt I had. Because for better or worse, I had always defined myself by what I could do, usually to help others. My strength always seemed to be my capacity to be effective, and in most cases, simply outwork any problems that came my way.
I eventually hit rock bottom. I didn't see the point in anything. I didn't have any hope, I wouldn't entertain any dreams. I wasn't sad, I had just given up.
What changed for me was I came up with an idea. What I like to call a "positive vision of the future".
I decided that no matter what was happening in my life, by the time I turned 41, whether I was rich or poor, sick or healthy, I was going to travel. If I had to work my way across the pacific on a boat, I was going to see Asia. Nowhere specific, and for no specific time. Just on Nov 1 2016, my life was going to take a new direction. And I had allowed myself enough time between the formation of this vision and it's realization, I felt I could give a good crack at meeting the responsibilities that had overwhelmed me in the present.
That's the thing about a positive vision. It is abstract. It doesn't require a ton of specifics, it's simply a way of seeing a future you, in a different circumstance, which feels attainable. My plan to travel seemed very attainable since I wasn't expecting to do it first class.
Did that happen? Did I end up traveling? Not yet. I'm only 38 and my positive vision has moved to being retired at 45. But that initial vision gave me what I felt would be enough time to get my life together, to be effective and to take some baby steps towards the larger goal.
So OP, what I would say to you is, get out of the house. Walk or ride a bike, or cab it or drive to a park. Maybe get a happy meal on the way. Go sit in that park. Just look around and have something to eat.
And think about where you might be in 5 years. Where would you like to be? What would make you happy.
If what you can come up with is attainable (no you're not going to be rich and dating a supermodel) then you're halfway there. You've got a direction, and maybe some hope and best of all, it seems possible.
You can adjust that positive vision of your future any time.
What's important, is that you are never without one.
That was my experience. YMMV.
