Lonely- (in my own words):

to be feeling cut off, away from, or with out feeling. This can be mentally lonely, like in a crowded room and you stlll feel alone. This can be physically, out in the wilderness camping or living alone in the city. There are many different forms and levels to being loney, to an extent we all need some alone time. But at the same time being social creatures exsessive loneliness does tend to... well, suck ass.
