How long should I be expecting to wait when emailing someone from the directory?

Hello. I've been trying to find support for myself for some time now, I'm having to do it myself and so far not having any success.

It's been a little over a week now since emailing a nearby group that I found in the directory here, but it's been even longer since emailing other local groups I found elsewhere. So far none of them have responded and it's starting to feel like there's just no-one available or my situation isn't being taken seriously. I've checked junk folders just in case, but still nothing.

Either way it's becoming incredibly frustrating. Unfortunately telephone simply isn't an option so I can't try that. Not really sure what else to do at this point.
