Been going through depression and anxiety for a while now myself, I can't offer any advice as it's not something I've really dealt with despite trying much.

I've always put off going to speak to the GP or counselling as I don't feel comfortable talking about these things face to face. However it's only getting worse and I shall be seeing the GP soon. A close friend has also recommended counselling and said it worked very well for her brother in law, just seems a bit American but maybe they have these things right.

Good luck with it.
