I'm so sorry to hear about your loneliness and pain you are going through. I have a similar situation but I'm 62.
You are never really alone. God is with you and inviting you to accept His invitation. I hate when my friend would say that , but it is actually true. God is always their. Does He replace humans,? No. But He certainly helped me through the loneliness by occupying my time with reading more and more about Him which gave me peace instead of anxiety. Do I still get lonely? Of course I do, I'm human, but it's less than it would have been.
I don't know where you are but I'm in Mass if you ever want to chat and discuss God , functional families, narcissists , or what have you. Lonely people reaching out to other lonely people = no more lonely people.
