TeenHealthFX is sorry to hear that you are feeling so unhappy with yourself. Feeling so alone and isolated can be very scary - you are very right in that you need to find someone to talk to.
TeenHealthFX understands that moving can be a difficult transition - especially when you move to a new country and are feeling far from your friends and culture. For many people a move like that can be a really tough transition, but at your age, it can be particularly hard since your friends no doubt play such an important role in your life. As impossible as it may seem, making new friends will happen in time. But before you can look to your peers for acceptance, you have to find a way to accept yourself.
Maybe talking to a therapist would be helpful for you. If deep down you feel every person is better than you, then your life is bound to be full of disappointments. The reality is that you are a special person, but if you are not seeing it, then therapy could help. If you live in northern New Jersey, you can get help finding a psychiatrist or therapist by calling the Access Center from Atlantic Behavioral Health at 888.247.1400.
If the depression becomes overwhelming and you are afraid of what you might do, please get help immediately. In New Jersey, please call Atlantic Behavioral Health's 24-Hour Crisis Hotline at (973) 540.0100. Outside of NJ, please call the Suicide & Crisis Hotline at 800.999.9999.
