Do you need to be entertained everyday?

I have a friend who can’t stand to be alone for
very long and has to invite anyone over to her
place all the time.
Sometimes she cannot get anyone over so she
calls in her grandkids, picking them up, taking
them out for lunches, suppers, weekends, even doing things for them that they could do for themselves.
Her bank account is very low and still she will not accept being alone for any lengh of time.
She has run herself ragged running around doing errands for various people in a seniors apartment block.
Its like she can’t stand her own company.
I feel that at times it is a good thing to be alone either with nature or painting or just quietness to get a better perspective on things for oneself.
But she seems not to be able to do this.
She is trying to fill in every hour with doing something.(anything).
Oh yes, she is losing weight at a rapid pace.
