I'm a 16 year old male, for the last year or so I've been feeling in an extremely low mood almost constantly, and it's getting worse. I always feel depressed, I get the feeling that pretty much everything is pointless, and I've become extremely pessimistic, I've gotten a lot more irritable towards people as well. I often think about suicide when I feel particularly bad, and the whole situation has made me feel pretty hopeless.
Since these symptoms started, I've had a lot of difficulty in social situations where I used to be ok, I used to be able to talk to anyone, but now I find myself with only a few friends I'm able to hold a conversation with. In an attempt to become more social again, I started drinking a lot and smoking weed a lot because it makes it easier for me relax when I'm on them, but it's just made things worse. Now I only really feel able to function in any social situation with more than around 4 other people unless I get wasted. So, this has made me pretty much dependant on drink and drugs to feel comfortable when I'm out. I wouldn't describe myself as addicted to either alcohol or weed though. I've cut down my weed smoking in recent months because I felt like it was making me worse, and I was tired of dealing with some of the scum you have to meet to get weed round my area, but now I'm drinking a lot more.
My sleep has been affected too, I wake up a lot in the night and never feel rested. My appetite has decreased as well, I often go for a day or two with only one meal, when I used to have a huge appetite.
I tried to tell a close friend about how I feel, and he didn't take me seriously and made fun of me a little bit. This has made me wary to go to the doctor's incase I'm not taken seriously again; I don't want that humilation again. I'm also worried that a doctor wouldn't be able to do anything for me.
I just thought I should mention that there have been two or three times where I feel almost back to my old self again for around three or four days, but I always feel terrible afterwards.
Please, I need some advice on what to do, I want to feel better.
