What you feel is completely normal.
You don't know exactly what will happen and thus there is a certain amount of stress.
The stress makes it all seem a bit bigger. But there is no reason for it.
Just relax and trust all will be ok.
There is no reason to worry or doubt. All willl turn out all right.
You had this feelings for a long time, like wanting to paint your nails...being girly...
just relax, it is there and will remain. It will not be there all of the time, and that is completely ok.
You can do some non girly stuff from time to time.
It will always be there though.
Just have some trust.
The mind often comes up with doubt. Just know that alll will be ok...
now that you know what it is, and that it might be a bit weaker sometimes but that it will remain.
Try to relax and do something you like... take a few deep breaths... and try to have some fun and a nice weekend

hugs
