I'm sorry you are struggling. I know that the side boards do tend to be a lot slower in general to get replies. It's also often generally easier to keep posts together in one thread so that people can get a better idea of what's going on for someone. Spreading posts out in multiple threads over multiple boards can be harder to follow.
I don't personally tend to respond to posts related to abuse just because it's not stuff I really have experience with and because they can often be triggering to read. I cannot speak for anyone else. But none of us are professionals. We're all individuals with our own struggles who have to balance our own safety as well when we look at things.
Not getting replies isn't an indication of your worth or to suggest you are not worthy of support. Again, these forums are slow, and also there is a time zone difference. Keep in mind RYL is a UK based site, so most members are posting during the UK day. That also tends to delay replies for those of us in the US as well.
Do you have any outside or professional support right now? Reaching out here is good, but if you're struggling that badly it sounds like you could do with some support irl.
