Loneliness makes me feel like I have no place to be and nothing to contribute, like I am a black hole sucking up air and space and giving nothing back.
If I have a purpose or an interest, I don't feel lonely, even when I am alone. The worst loneliness is the loneliness of being misunderstood, or overlooked and cast aside by the person who is supposed to cherish you.
I reach out a comforting hand to you, OP. There are so many people in their separate homes, often 'leading lives of quiet desperation' - many of us need connection and mutual purpose.
When I am lonely, sometimes I stroke my head gently and remember how it felt when my mother did that. She was not an openly affectionate person, and she was difficult and unhappy, but when she was old, she used to gently stroke my head with her gnarled, weak, arthritic fingers, and it felt like the opposite of loneliness. Can you do that for yourself? Or a similar gesture that reminds you of a love that is unconditional and infinite?
Do you remember the 'mind my worries' thread on mumsnet years ago? Maybe we can mind your loneliness.
