Scared of checking my emails

Hi! I’ve been having challenges with a couple of colleagues and after some difficult emails, in which demonstrably untrue allegations were made about me, have decided not to read any emails addressed to me by one of the colleagues as they’ve escalated and I have created a boundary for my well being. My issue is that any ongoing work with this company requires engagement with these two colleagues. I am scared to open the emails. The thoughts I have are: they are going to attack me; they are going to unfairly criticise me. I feel scared, anxious. I do not engage. But I have to, so instead, I feel trepidation and anxious when I am included in correspondence. I do not think I am attacking or unfairly criticising them or myself through this action. I’d like to get to a point where I feel empowered but their lack of engagement +/- hostility is a bit challenging. I’m having a hard time coming up with helpful news thoughts.
