Hi my bf has a tradition of going on a holiday with his two best friends for 15 to 20 days and this year it’s 16.
And I cannot deal with him leaving me for so long. I know he loves the trip. 
I would hate it if he stayed at home just for me being difficult but it still makes me so mad and angry that he’s leaving. I feel super bad, selfish and evil. 
Do you guys have any advice on how to get through this without a bad episode? 
I’m trying to make as many plans with my friends as possible so I won’t be alone for long but still. 
Thank you guys :))
