Hi needmore, welcome to the forums.
The best place to start would be by having a good look around this website - there's a lot of great information about what depression and anxiety is, available treatments and where to go for help. Have a look under 'The Facts' menu at the top.
Here on the forums, you'll find lots of people who have personal experience of living with and recovering from anxiety and depression if you would like to talk through what's going on in your life and how you can take steps toward your own recovery. Have a read through the threads in the different forums, contribute to the discussions if you would like to, or start a discussion of your own.
Hope to see you posting more again soon.
