Okay so recently I've been really depressed for no reason at all. Like I can't be happy no matter what anymore. For example I love fifa when I play it I use to be happy now still depressed. I also just 2 weeks ago always wanted to hang out with my mate now I never want to. Just seems like everything is such a drag now and I feel so down. 
I've done everything I enjoy to try and be happy but i can't! (I can't bring it upto anyone either my family is under the impression depression is fake)
Last year I had really bad health and death anxiety which I still have now but alot more tame
I'm 16 and a male if that helps. 
I really don't know why it's happening and I just wanna be happy. I wanna enjoy been with my mate but I can't.
Please someone help
