It is an energy that feels good & feels alive. When one doesn't have it life is dull & there is nothing to live for & lack of it can make a person sick & even die.
I get really depressed because I am not loved by anyone. I do have someone I love & that does keep me going though.
It's very sad to not have anyone love me. I used to do a lot for others so that I would be loved but I got sick then couldn't work then really got into a rut so my life feels hopeless. If I had people that loved me they might even be able to help me so I could get a job or car or some way out of my rut so often having love alos means have support in life.
