Hey Charlie,
We'll all say what' wrong time and time again, so thank you for making us feel like we can give back from what we all take from!
I can only give personal advice, and what works for me. When I'm in a complete stump, where nothing helps and everything seems to get worse, I go into a room by myself, or anywhere where I can be by myself. Then I meditate. Sit down, realize we already know the thoughts are making it worse, so sit, and think of nothing. Every time a worry or even a thought, good or bad, comes to mind, stop, purposely fight back, challenge it. Instead just let yourself feel whatever your feeling. As bad as it may be, just let yourself feel it. Then start the belly breathing, still maintaining the mindset that you will think nothing. Only let yourself feel, whatever your feeling. Keep with this until you don't need to fight back the thoughts, and can just feel. How does your body feel, go into as much detail as possible, "I feel my hand trembling, heart thumping..." whatever details you feel inside.
Once you reach this point where you only feel, think of where you want to be, then let yourself imagine this place. Remember it's your dream, you don't even need to be talking or anything, you can just picture yourself having fun, relaxing, whatever. This is where my meditation gets interrupted and everyday life kicks in. Doesn't solve the problem, but makes things bearable.
