Can I recover? My story.

Hey guys! I'm 16 and have suffered from depersonalisation for a year and a half. I believe it was initially triggered by my depression/anxiety and also from drinking and smoking pot.
It's been the hardest thing I've had to deal with and I hate to think that there are people like me who have to suffer from this, it's honestly so hard. I'm starting to think that it's not going to go away. I would do anything for it to go but I honestly don't know what I can do anymore. Can anyone help me?? Thanks so much, poppy

There are some videos on youtube that explain how. I am not sure if they are helpful or not. Also if all else fails go see a therapist.
