I'm loving the sound of me giving zero fucks about the unpaid project I stopped feeling responsible for. It's so peaceful. 
Of course there's still the odd moment of screaming into the void. 
The recovery process is a work in progress. That too will pass. 
Have you discovered the joy of dumping thankless jobs that were getting you down? 
Hell yes! Recently a “paid” gig through an agent. Accepted terms I would not have myself - worked my butt off then dropped it when the client suggested I should just copy a grade 1 craft from Pinterest ( it was not appropriate for the brief). 8 weeks after the job was acccepted, client had not even chosen the main colour for the design. Why did I spend any time on it? Sometimes I’m an idiot. Felt so good to just walk away, even with the burn.
Well done for quitting your horrible unpaid 'paid' brief.
I'm sorry you had to go through that.
Admitting the reality of our situation is hard enough and sometimes walking away is the only option.
It looks like you had a feeling the terms were unreasonable from the start.
What will you do differently, if you are offered something like that again?
