It stinks to feel ignored.
Please remember this is a community of people also struggling with their own stuff too, who may struggle to just get to the site too. It's not a professional therapy or crisis intervention service. You probably already know this, but it's important to remember this is a peer support site. The folks here are your peers.
I suggest looking into other possible interpretations as to why there is no response at any point in time. Those that you feel are intentionally ignoring you could actually be in their own crisis or struggle just to survive. They may not have enough speed or don't feel comfortable in the environment of chat for their own social anxiety reasons. We are peers with the many of the same battles.
If you are going into chat and posting something like "hi" and nothing happen for a long time, well, that's normal even for those who talk in chat all the time. The section that says "members in chat" is not a reflection of people actually looking at the chat the chat screen at that moment. It's not like everyone is logging into chat thinking "oh not the new person, umma just gonna sit here and ignore you on and on and on."
I challenge you to undo these belief that all these people are more capable than you and don't respond out of intent to ignore you or anyone else.
I also would suggest that this might have been a more productive thread if it would have been posted to ask how chat works, why don't people respond, etc. it's kind of a little push/pull and passive aggressive to come here and anonymously insult everyone you actually want support from.
You did at least get quite a bit of response and attention here, so I hope you can see you are certainly not being ignored.
