a real way to cope with loneliness

i am on my own apart from my elderly parents who live an hours drive away...i live by myself, in a one bedroom flat, coped with mental issues all my adult life and never established adult relationships...i do get/ feel lonely a lot....i know the world won't come and find me.....so what can i do?

i had a great youth/childhood, but my adult life was hard.

i am an introvert, but still hope to find some relationships & friend or two...i am now in my mid 40s.
