I know exactly how you feel
I'm 15 and I feel like life is just pointless, I drown at night in so many sad songs
Smoke a lot nowadays, losing friends because they feel I'm a drag, things like that you know
Depression is a reality that should be addressed. It has nothing to do with what you possess or what your interests and activities are. A lot of people suffer depression for no reason at all. A proper counselling session would be enough to tackle your problem. Cheers!
Depression isn't a reaction to anything -- you're confusing sadness to depression. Nobody knows what causes depression or anxiety or PTSD. A hundred people can go through the same thing and only one might suffer a chronic emotional reaction to it. People are just different, and there's nothing wrong with that. If you need help, you need help. Your history suggests something in your life has left you feeling insecure. Nobody can tell you why unless something traumatic happened that you aren't remembering, but you don't have to continue thinking that way. You can learn to think differently. Good luck.
Obviously you have low self worth sometimes. If you look at your life and compare it to others there is always going to be a problem. I am a veteran and when I returned from Iraq I had PTSD but didn't know it. Even when I was experiencing symptoms of it and my life was going to HE11 I would not allow myself to accept it because "I had not seen what other soldiers had seen." A lot of soldiers come back who have seen some tragic things but won't admit they have a problem because we compare ourselves to other soldiers thinking "well this guy had it worse" or "this guy killed a lot of people" and they are fine so there can't be something wrong with me.
I learned after I finally gave up and went to the psych hospital that it isn't just the ones who see and do the most horrific things who suffer from PTSD. I met soldiers who had horrible stories, yet they had a family, a job, and none of it seemed to bother them. I also met soldiers who just saw once incident and were totally messed up.
The point is- I don't care how perfect your life seems. There could still be a need for you to seek treatment because not only are all of us different, depression and mental problems are genetic and you could have received things like depression, bipolar, and so on from either your parents, their parents, their parents and so on.
There is a movie I would like you to see if you have not already. It is called "It's a funny story."
I believe you could relate to that and that movie would touch you. I am not going to tell you the whole thing but it is about a guy who has a great life but is still suicidal and depressed. It is noticed by his family and he is checked in to a mental institution for a week or so. Mental institutions have a stigma on them because of movies like "One flew over the cuckoo's nest" and others but a lot of them are not bad at all and can really help. Also seeing a therapist has a bad stigma but you should never be afraid to talk to one. Maybe even your guidance counselor. If this troubles you enough to come on here and tell us then it is a problem and unresolved problems do not go away, they get worse.
I am not saying you are batsh1t crazy but you may need to start seeing a therapist for a little while so that you can understand what is going on with you.
Anyway, if you get a chance watch that movie. I promise that it could change your life.
Dreams are meaningless, so you can ignore them.
I can't diagnose you but it seems you could benefit from someone who you can talk to who is a professional, in order to figure what is bothering you.
Have you ever had therapy, how old are you and if a student can you see the school counselor?
A lot of what you describe seems to be just overthinking things, so you might be surprised at how much better a therapist can make you feel just by pointing out some suggestions.
