I agree with Happy here. When I am stressed things come out formed and are difficult to get out the next day.
Not easy to destress Pinky, but try. I guess you have a lot on your mind now...
When I went on a holiday with fissure last summer I had to change things in my head. Instead of thinking of all the bad things that could happen to me and my lovely fissure companion, I thought: "It will no kill me, I know what this is and I know how to pamper it if it gets really bad (= rest, fissurefood, water, etc...)".
Tell your family that when you get there, you need a lot of rest the first days to recover and that they need to help you with your son...
Good luck Pinky.
