How to become more motivated?

I'd say this sounds like you're still suffering from depression, as lack of motivation is a big, big symptom, one of the first things GP's usually ask is, 'do you still do things you used to enjoy doing?'. GP's are usually rubbish at diagnosing mental issues, but hunt around, and explain to the GP you've not had much help elsewhere, and they might be more likely to help you. Hope you're okay x
