what is this feeling?

Do you also feel a sudden loneliness?or the feeling of being alone it seems you are trapped to a room that no one can help you sometimes I do, but what does i really feel?is this the sign of boredom or a sign of my insanity?. Lot of questions trigger on my mind and i can't find the answer until i realize i am totally helpless, why i am holding on if i know at the end no one can really help me that no one really cares, will they still remember me if i will be gone or all alone with my disappearance is also a forgotten me.
