My dear, I am very sorry that you're struggling. Unfortunately, it's not a very good idea to speak to strangers on the phone on this site.
Could you let me know what country you're in? There will be support numbers you can call to calm you down... The UK Samaritans is 24/7 and I have spoken to them before to bring me out of a panic.
You've reached out to us which is good and means you don't want to harm yourself but I'm sorry it's a tough night - it's never easy to sleep when you're distressed.
I am happy to speak via private message if that could be of any use to you.
