It's ironic that people like me have such a hard time with churches, even though we're the ones who need it the most (it's not the healthy who need a doctor and all that). You'd think that churches, Orthodox churches included, would go out of their way to reach out to people with special needs and make things easier for us, since we're the ones who actually need it the most and we'd be the most likely to keep attending as long as we had the necessary support. But it seems like no one cares about us, they only want the "normal" people who won't take up too much of their time or energy.
Unfortunately, that is often true, and it's good to call that out, if only to recognise how regrettable and contrary to the gospel it is. But in most cases, I don't think it's a matter of "no one cares".
I think miscommunication or lack of communication is a big part of it. As a parishioner or a cleric, there is a reticence to be too nosy with visitors lest you turn them off, and so they're waiting for the initiative to come from the visitor. As a visitor, you may want them to be nosy so that you have an opening to talk to them about your needs, or you may appreciate their respect for your space but at the same time feel like they wouldn't care about your problems. So no one makes a move.
I've been in situations where the clergy and/or the parishioners just don't care, so I know that's out there. But usually, when I open up, I find that they are quite receptive and helpful. I've had people offer me rides to and from church events, offer to come over and cook for me when I'm sick, help me with repairs and other house work, etc., and often it's the parish priest who, hearing that there's a need, takes it on himself to help me himself or find someone in the parish who can help me. And I've volunteered to be that person as well when needed. People just have to know there's a need, and they'll usually figure out how to address it.
Which brings me to another issue: we are not very imaginative. We don't do well without an actual person to deal with. It's one thing to suggest that "Maybe there are people in the local area who would benefit from X", and another thing for "Mor" to show up and tell them "I'm a person in the local area who would benefit from X". I've seen this at play in parishes. The clergy and/or the parishioners may suggest some sort of general need that should be addressed, and they might brainstorm for a while, but whatever plan they come up with ends up stalling in a way it doesn't when it begins with an actual person or group and his/her/its needs.
We're not perfect, and that's not an excuse. But I do think a little openness, communication, and good will from all parties go a long way.
