Your best bet is your friends. Have people check in with you regularly. If you have to go to an ER. You probably won’t feel this bad for a long time since feelings this intense usually dissipate. Our feeling come and go. They are just feelings, thoughts -remember that even though they seem powerful. That said, you sure don’t want to go on feeling like this in the future do you? I hope you will find supportive people or professionals who can help you get rid of this form of pain.
I find that what gives me these kind of feelings is telling myself something like – what is happening now is the opposite of what I wanted to happen in my life and it’s not going to resolve or get better. Or maybe thinking that your main purpose in life has been blown away. It’s my expectations. Try letting go of your expectations for a day or a few days. You can always get them back if you really want them.
