Life would be very difficult if there is no love in it. Humans are called social animals, and the reason is that every human being needs another human being; One cannot live alone. If one does, it will make them depressed. It has also been shown in research that loneliness can lead to major depression and even suicide.
Life is difficult, and to deal with day to day hassels, one needs emotional support from their loved ones. If you have your loved one near you, you will feel secure, and only then you will be successful.
As Louise Erdrich rightly said…
“Life will break you. Nobody can protect you from that, and living alone won’t either, for solitude will also break you with its yearning. You have to love. You have to feel. It is the reason you are here on earth. You are here to risk your heart. You are here to be swallowed up. And when it happens that you are broken, or betrayed, or left, or hurt, or death brushes near, let yourself sit by an apple tree and listen to the apples falling all around you in heaps, wasting their sweetness. Tell yourself you tasted as many as you could.”
