@Lucy I'm the same. Hysterical most days. It's awful.
I have similar mood swings, worrying about all things and how my life will change and sometimes cry but I think it’s also hormones and I have been less active / seeing friends than usual and have not been travelling which I normally do so I think it’s normal but I don’t have advice on how to solve it just so I feel the same and imagine some of it is caused by the fact it is such a big change in the life and hormones.
Don’t worry you’re not alone, the smallest things sets me off at the mo! X
