Am i getting depressed?

if you read my other two questions you will know what is up. so now after all that i feel like nothing i only feel sad and a bit mad. there is no joy in my life. i never feel like this i am a really happy girl. but now i just want to fold my self up and trow me out the window. i am not talking to ppl. it is like i want to live of the moon so one one has to see me and i dont have to see them. i do not know how to tell you how i feel it is just a lonely sad cold feeling. i do not feel like eating at all. i am crying all the time. i just dont want to live... but i dont want to die, i want to get better. can you help me? but what i want to know is if i am getting in to depression? no mean things. i do not think i am crazy... do you?
