Hi
You are always welcome to chat on here if you are feeling a bit alone. But the commenters here saying we need face to face in person relationships are right. It doesn't solve your problem though. I hope and pray that you can find local safe connections with believers, and friendly, well-intending and God fearing people online in the mean time.
I want to encourage you that Jesus sure knows what it is like to feel alone. So did many of the greats in the Old Testament, and New. As do many Christians alive today too. So you are ironically - in good company!
Jesus had 12 followers who probably knew him better than anyone on earth, but they didn't REALLY know Him at all. He couldn't be 100% open with them, and in His darkest hours when he reached out to them, they fell asleep, and then deserted and denied him.
The most beautiful thing is that we have a Saviour who never leaves or forsakes us.
BUT Jesus called us to love one another. To be literally members of the same body. To be so close we feel what one another feels -literally. To have FERVENT - WHITE HOT - LOVE for one another. To prefer one another to ourselves. To seek the good of the body and not ourselves. To make ourselves poor that others may be enriched. To pour out ourselves that others lives may become fuller. Hard to do that when its a hand shake and a few polite sentences with a few people each week at church at the best.
Jesus put that desire in us to be with one another, because HE dwells in His people, and we want to be with Him.
If we don't want to get to know any of God's people, to open our lives with them and share their lives also, at the very least as any real earthly family would, then in short, we do not love Jesus.
Be encouraged. The desire you have is a sign you love Him and want to be with Him.
Many of us have found it hard to make face to face connections that are deeper than the brief pleasantries we tend to experience before and/or after church gatherings. It isn't deliberate I am sure, but I find most people are very worldly in their attitude to "their own time".
Make of that what you will, but I personally have never needed to make an appointment to see my mum or dad or siblings, or anyone who lived in our house, and yes if they are genuinely busy with responsibilities, I help out or if that isn't possible, simply leave and come back later. I assumed upon becoming a believer that the church would be that family we find in Acts, eating together daily and going house to house in fellowship and so on. But alas, it has not been my, or many other peoples experiences, and the few rare places I hear of that have such an ethos, seem to turn out to be cults sadly.
We have to be the friendly one, if the church lacks such people, and hope that it rubs off. I do warn you though, prepare to be treated with suspicion if you try this. People don't seem to be used to anyone wanting to open their lives to other people.
I have no idea how people bear with one another, or carry one another burdens, if they hardly know one another. If I stub my toe, my whole body reacts and is incapacitated until it eases. Where as the church has multitudes of hurting people and the majority of those even in the same congregations often are clueless to it and carry on as if everyone is a ok.
I have no solutions, but I do pray that you don't grow weary of trying and please dont let anyone put you off reaching out in love. I have found a few individuals over the years, precious and wonderful people, introvert and extrovert alike, who really accepted the hand of friendship when it was offered. They have changed my life and are genuinely as much my family to me as my own blood kin are. The few you will find on your search are worth all the rejection and weariness you may experience along the way. Don't give up. The church needs you.
Be the love you seek in others. Be the offer of a friend who sticks closer than a brother, even to the brothers who may not really recognise or treat you as their own family. Look for your completion in Christ alone though, and you will find strength to keep on being the friend you seek, to the friendless.
