Hi there @BvB
It can be really tough having to pick sides in a friendship breakup. Both sides may still want to be friends with you, and may want you to stop being friends with the other. This can be difficult because you don't want to let anyone down and you may want to keep being friends, which can cause some anxious feelings. I can see you're feeling really overwhelmed with all of this, and with all the pressure you're feeling from (G) to stop being friends with (D).
It sounds like you still want to be friends with (D), which is causing the overwhelm. Olive_Penguin commented and spoke about boundaries, which I think is a super relevant point. I think it's important to remember that you can only do the best you can, and you can't make everyone happy in this situation if you want to stay friends with (D) (which you are more than allowed to do, other's can't dictate who you can be friends with). I think it is definitely important to take time to yourself to think, especially if the situation is causing you so much anxiety.
Regarding boundaries, it could be useful to have a frank conversation with (G) just explaining that you understand that this may be upsetting for her and acknowledging her feelings about this topic, you being friends with (D), but that you want to stay friends with them and this has been a really hard decision for you as to what to do about the situation.
In the meantime it's definitely important to remember to look out for yourself. Are you doing anything to take care of yourself at the moment, as it sounds like you are quite anxious about all of this? Do you have any methods of self-care that normally get you through difficult times? For example, sometimes when I'm feeling stressed I like to read books or listen to music and meditate. What do you like other than do when you're feeling this way?
I'm wishing you all the best 💜
