Hi, since the age of fourteen (I'm 18 now) I have suffered with depression, anxiety and Depersonalization Disorder. I got DPD from a panic attack whilst smoking weed, it caused me to feel disconnected and detached from myself and the world around me. It's so strange, it's impossible to explain it to someone who hasn't experienced it. Everything looks and feels fake, like you're living in a dream. But as a direct side effect from that, I became really anxious and depressed... Too scared to leave the house because outside looked weird, and too scared to speak to people because they looked weird, etc.
