I recommend against taking your Paxil; antidepressants don't work for mild depression.
Running is a good idea; exercise, sunlight, and being outside all help.
Avoid dropping responsibilities, and if you must drop small stuff first and responsibilities to others last (so quit showering before you quit working overtime). Counterintuitively, you should keep yourself in motion and having hard stuff to do and triggers to do it everywhere; otherwise recovering is much harder.
Changes can mess up your trigger network, but generally help, especially when of the form "get out and do fun but moderately effortful thing X". If you find you're enjoying yourself more than current average, you're doing it right, regardless(-ish) of absolute levels.
How introverted are you? More social interaction is generally good, but demand alone time if it starts to drain you (can be hard, since you're married). In general I've found that quality of interaction is crucial (YMMV a lot): minimize being alone in a crowd, maximize the number of people who know your preferences and time spent with them. Love languages are a good first approximation.
By the way, I'll see you in-person at the meetup, so if you'd like a hug or a present or a chore done, be sure to ask.
Antidepressants are more likely to bring remission in mild than in severe depression, it's just that their superiority to placebo is slighter. Antidepressants are also vastly better than placebo at preventing future depression when their use is continued after remission. Beware the linked article, which is hopelessly underinformed.
My girlfriend suffers serious depression. She has sleep disorder, anorexia, chronic pain, problems to concentrate, low selfesteem, daily low mood, listlessness and is very indecisive. On the other side she considers herself very happy apart from the "depression periods" and we have a great time together. We already consulted a psychotherapist, but there is waiting time about one month. I buyed her fishoil capsules, because she eats no fish and there is mild evidence that it helps treating depression (I don't think this will affect her depression greatly, but fishoil seems like an overall good idea). We often go on walks to catch some sunlight and get her some exercise.
She says she never want's to take antidepressants because she fears to get dependent from them. I think she might change her mind if there are very good arguments in favour of them. She is quite rational in spite of not knowing the LW-stuff. Does anybody of you know if there is any information of the succes rate of medicamentous (and psycho therapeutic) treatment available?
I highly appreciate any advice.
Furthermore i want to call attention to the topic of depression. A huge share of the population suffers at least once in their lifetime under depression (~20% in Germany). Sadly it's often not taken serious and a big taboo to speak about. Many people see it as self-inflicted. My girlfriend's mother doesn't believe in depression as a disease (see diseased thinking). It's a paradigm of irrationality that hurts people.
