I don't know what is wrong with me please help me!!:,(?

I am a 14 year old girl and I need help. For close to 3 years now I have felt that im living life through a dream or a haze. It is really hard to describe. I don't feel normal or here on earth. My body feels like its numb (ex. before when I felt fine I would touch something and feel what I was suppose to like if it was really hot or really cold I would feel just that and now if I touch something like that it only feels like its luke warm and not very cold same with object I know they are there but they don't feel there.) My mom thinks it may just be bad circulation also so I don't know. I also get nervous a lot and always feel anxious or panicky especially if not always in public. Before taking zoloft I only got those attacks at night and in public but now since taking the medicine I get them during the day. When I feel in a dream and anxious and clumsy and it feels like im suffacating. It is really uncomfortable and to the point where I can't stand it. There hasn't been a moment where this has gone away. I think I might have depersonalization or derealization disorder (if u don't know them look them up) , anxiety and social phobia. If you can help me with this problem I will be forever greatfull!! I have been sufering this for 3 years please I need your help I don't want to let my life keep ping me by!!!:,(
