Hey Turquoisesea,
Don't know your background but understand depression can be tough no matter the cause. From my experience I only say that this difficult time will pass and hanging onto hope that a better time is in your future is important. Simple tangible ideas to focus on that I have found to help is: finding gratitude any where you can like your physical health, family, home, you can read and write; reaching out to people that offer positive feedback and comfort; helping others where ever you can.
Hope you feel better soon
