I've been depressed (but also not - I'm 'lucky' in that my depression is/has been situation based rather than innate/chemical). I think the problem with chasing happiness in particular is that it's kind of similar to chasing the high of a drug: It's not possible to be actively happy 100% of the time. I know in my depressive times one thing I liked to do was set myself impossible goals, and I think 'being happy' is one of them.
In my case, I needed to be more in touch with my emotions because I have severe dissociative issues and a very adversarial relationship with my own body, but I don't seek out any particular emotion. I see my emotions as data being passed to me from my lizard brain and I believe that to make appropriate decisions I must pay attention to all relevant data. In the same way that when planning an outing I must consider my physical capacity, when planning a goal or project I must also consider my emotional data. I try not to ascribe meaning to the emotions themselves, but I view them as invaluable indicators of meaning. If that makes any sense.
