I'm new

Hi everyone, I just signed up and to be honest I haven't a clue what to do or how it works. 

I've had quite bad anxiety for almost 4 years, which has resulted in a lot of "sick" days off school, I have been in and out of therapy and always seem to get on the right path bit then I end up becoming weak and falling back to my old anxious ways. 

I had been on the right path for almost a year as I had met some new amazing friends but right now I don't know what's happened I have slowly become more and anxious (which I can deal with) but this time is come to me with its friend depression which is an entirely new feeling for me and I'm becoming lost and scared and don't really know what to do. I've spent almost my entire summer on my sofa watch the same TV on repeat. 

Sorry that's the first time I've ever actually wrote that or told anyone. So if any one has advice on either dealing with this problem or simply how to use this website more efficiently, it would be grealty appreciated.

Thank you
