Loneliness

So I have one question. If we can love someone so much, how will we be able to handle it the one day when we are separated? And, if being separated is a part of life, and you know about separation well. Is it possible, that we can love someone and never be afraid of losing them? At the same time, I was also wondering. Is it possible that, we can live our entire life without loving anyone at all? That’s my loneliness. I have lived with it now for 10 years; I know just how bad loneliness feels. I fear it will continue to get worse.---Mew
