The absolute rock bottom incontrovertible point is... you're worth this effort
Your future is your hands.
If you want some, or all, of the things you mention, you need to stay sober.
Drinking consigns you to this kind of existence - miserable when drinking and miserable when sobering up.
It may feel like this week goes on forever, but it doesn't.
Odds are you'll feel better by the weekend
Get outside and get some sun on you - do some stuff. Play some tunes. Get busy living.
