That's true, sometimes in our life we just feel like we need to be left alone just to think and to know a way forward ,most of the time we feel lonely not because people aren't around us but because we feel that whatever it is we are passing through might not be understood by someone else so we think the best option is to just to let it be and be left alone well that's actually not the way you supposed to be when this time comes it's usually better sharing the problem with perhaps our best friends or even family as the case may be, just as the saying goes" a problem shared is a problem solved"but when we keep it to ourselves the problem will still continue to be there so it's better to let it out and get a solution. I wish you a good night rest bro, it's still around 8:32 over here, and do take care of your grandmom.
