Hi Thanks for your approach. i am sorry for your situation,  if you are unhappy for a long time it doesn't mean that you are in depression state. Try to know reason for feeling lonely, unhappy and other emotional disturbance. May be due to this you are not able to handle your self or situation and vice versa. I do understand most of the time when we want to share our emotions, we won't find anybody, but simultaneously we can try in handling ourselves. You might capable of handling your self. Just need motivation and guidance, you can visit psychologist for any kind of support. Take care stay positive.
