Sadness and feeling like dying

Hi Coaches,

I am in process of making a decision to end a relationship (short but deep) and when I think about not continuing this relationship with this person I feel an immense sadness in my heart that almost seems unbearable. Of course I stay with this emotion and it eases but the thought I have that scares me is that it’s going to come back and because my brain knows it’s painful I start to freak out.

How can I think about this in a way that will propel me forward? I think I also feel shame/guilt towards myself because I am ending this relationship knowing I don’t have the emotional or mental capacity to truly be present 100% for it and therefore don’t really believe it’s the right choice, even though physically my body is saying I’m burnt out with things that are going on leaving me no choice…

Thank you.
