What if I really can’t handle an emotion?

I’ve been in coaching long enough to understand and believe that emotions are better handling by allowing them. But I’m really struggling right now. Due to some family situations (which I know on some level are neutral), I’m feeling immense emotional pain, worse than I have ever felt. I haven’t gone to food and I’m trying to allow it but I can’t even get out of bed and I feel like I’m going to die or implode if it doesn’t get better soon. I’m trying to observe the pain and allow it but it’s way more painful than anything I’ve ever felt. And I know that if I’m still suffering an emotion, it’s not time to change it with a thought (and I’m not sure I’m ready to believe anything new anyways). Please help.
