You're an introverted guy, right? And you were single once, yes? Maybe you never experienced the presumptuous married type that assumes you are all lonely and sad because you aren't married like them- and reassure you that you'll be happy just like them someday (lol). If that's the case; I'm glad for you.
More importantly, by posting this in the family forum; you acknowledge that loneliness is not a singles-issue: it's a "people" issue. There's plenty of family-folks that are secretly lonely in their family life, when they thought it would bring fulfillment.
Sing to God!
Sing praises to His name.
Exalt Him who rides on the clouds—
His name is the LORD—
and rejoice before Him.
A father of the fatherless,
and a defender of the widows,
is God in His holy habitation.
God settles the lonely in families;
He leads the prisoners out to prosperity,
but the rebellious dwell in a sun-scorched land.
