Hello 12crs,

Yes there are a lot of resources on the internet to help you cope with depression. Psych Central: Depression

There are a lot of things we can do for ourselves to get through it. Over the years I have built up my own depression 'toolbox' of coping strategies to get through those darker times. You have to find out what works for you. For example it has been proven that exercise helps with depression and so does sunlight, so going for a walk (even when we don't feel like it) in the sunshine can help. Eating right and getting the right amount of sleep, sounds simple but when we are depressed we are less enclined to take care of ourselves.

As for your second question, therapy with a professional is best but yes we are social beings and sharing/talking about it really does help. Bottling it all up makes depression worse so talking with friends and trusted individuals is a good idea. And of course the forums here are useful for sharing as well - another self-help resource!
