Something to keep in mind is that you DO have friends you can reach out to. Threads here are not the best or most interactive places to go for support, honestly. They can, as Jess notes, rapidly slide down the list on a 'feed' and be missed by others. Folks might gloss over a plea for help, in their own search for help and information. Some folks may not recognize a plea for help through their own filters, and may respond in a very inappropriate way. (Been there, bitten by this!)
I think it is absolutely vital to build one's own support network, friends one can phone, Skype, or otherwise rapidly connect to for real-time aid. I would strongly suggest NOT using a text-only medium like texting, e-mail, or message boards when one is in distress, because it is far too easy to misinterpret, misunderstand, and just plain miss cues and signals that are present in voice and expression. Most of us are not exactly Hemingway when it comes to our writing, and are not that great at communicating nuance in text.
I'm often around via Facebook Messenger, FaceTime, Skype and even the telephone to connect and support others. It's OK to reach out.
