Do I have depression?

I am 16 years old and my younger cousin used to live with me and my family for a while. He was like a younger brother to me and we pretty much did everything together. Every weekend he would go and visit his dad and and come back on Monday. But suddenly his dad decided to move and take him with him. Shortly after he left I started feeling very sad and lonely, I was bored because we did everything together and it didn't seem the same anymore. Then on the 26th of February this year I was sitting in church and I all of the sudden felt like I didn't enjoy anything anymore. It is very hard to explain, it was very sudden, I just started to think about things I enjoyed and I did not feel any enjoyment about them like I used to. Then the next day I became dizzy and that lasted for a while. I also experienced vision problems. We got blood work and a CT scan but they couldn't find anything wrong. The dizziness eventually went away and the visual symptoms are getting better. Now I just feel like nothing is the same anymore. Home doesn't even feel like home. I don't enjoy anything like I used to. I feel like I've changed and I will never feel happy or enjoyment again. I just want to feel pleasure in things I used to enjoy. Also I have had memory problems and I have been doing poorly in school because I can't concentrate. Has anyone felt like this before and will it ever go away? What should I do?

If it is depression how should I go about getting it treated, and will it go away?

You might just be depressed, like it's been said above, because your boyfriend went away.

That is very depressing.

But maybe they call that, situational. Like, you do poorly on a test, and you feel bad about that.

Like, my psychiatrist, who treats me for bi-polar, like I get manic and I get depressed with my medicines.

So, then my wife passed away from a long illness almost 8 years now, and the first few years were kinda tough, and my psychiatrist was saying something like,. get over it.

What helped me the most was, I would have like a health care worker come in a day or two a week. And in talking to them, and them taking me places, I would start having a life on my own, rather than the life I used to have with my wife.

And in so doing, my psychic did not so much long for the past, as it looked forward to the future. So, in getting out, going to school, volunteering, whatever, you meet other people and situations, and they can take your mind off of the past.

People, activities, projects, it's what helped me, anyway. And wasn't my psychiatrist glad.

Since you go to school, don't you see a lot of people everyday, and there's a lot to do. You're in a good situation to do that, being around people all day.

Do you have a fellow student you can confide in? Tell that person your troubles?
