Your symptoms are too complex to answer from an internet site. You need to see a internist, psychiatrist or psychologist to evaluate your symptoms.
I was having a conversation with 2 of my friends and I don't think it was related to me or my life at all. Keep in mind when I socialize i'm mostly exploring my own thoughts rather than investing 100% of myself to any convo. It's very difficult for me to carry convos most of the time..sometimes it's the easiest thing.
But anyways I was just thinking about my past/current life a lot and just snapped out.
what caused you to suddenly "wake up" after living all 18 years of your life in a confused fog?
