had before Christmas a painful break up with all my friendship group, and my best friend. I’m a teen and due to covid I’m only going back to school next week. Which means I’m going to see them all, and see how they all completely hurt me. whenever they get mentioned I seem to have a panic attack, like I feel like I can’t breathe, get shakey and get anxiety whenever they are around. also in places that remind me of them being up these anxiety moments. also it’s started getting physical symptoms like feeling nauseous all the time. any help on how to overcome this??? sorry
