I am at a weak point.

[Ryantology]

I have heard religion described as poisoned mother's milk. In other words, if you are raised in a religion, and your social capital is derived from that religion, it is even more difficult to separate yourself from it.
This is my problem.

I am in a situation in which I have no family I can trust, not because they are religious, but because they are dysfunctional and have major issues that prevent them from being a supportive network. I am often tempted to return to religion and join a church, not because I believe the teachings, but because I need a close-knit community to belong to, especially when life gets rough.

Any ideas?

Trading one dysfunctional organization for one which is certainly worse won't help.

There are countless groups and social circles in which one may find what you're looking for without having to submit yourself to the misanthropy and backwards-thinking of a place of worship. Whatever interests you have, there's probably a group talking about it.
