Hiding and neglecting things indeed won't help all the time. Maybe you could take a couple of minutes to explore your depression, try to think of the reason why you are feeling low. Maybe that reasons are something you can accept, or turn into something positive. To give you an example, one of the many reasons I was depressed was because I never had a girlfriend. By exploring my depression, I found out this played a role, and made me think about it. I found out the real reason why I wanted a gf was because I thought that was the only one who I could share my secrets with. Well, that isn't true. I also found something positive. If I had a gf a couple of years ago, I would probably a very bad friend because it just happened as soon as I started to think about it. Now I had a lot more time to think about it, so I believe I will be a much better friend. Also I will cherish the friendship more, because I know what it is like without.
Anyway, the point that I'd tried to make was that most causes of depression have an alternative "Cure" to it. For the gf thing, it was simply to trust a few close friends and share my problems with them. So maybe exploring the depression can help you as well.
One thing you can do though to improve your sleep and mood is exercise. Being physically tired will help a lot in getting sleep. And exercise also has a nice effect on your mood, as the neuro-toxins released will trigger "happiness" (yes, they do!)
I am sorry about the Effexor as I don't know much about the meds, but I am sure others on this forum will know.
Take care Unhappy!
