Hm...
I think you're getting upset over nothing
about not having a personality. Of course
you have one and your boyfriend clearly
loves you, so don't stress over that and
try and calm down.
I'm a strong believer in being semi
dependent from one's partner. No hobbies?
Just find something you enjoy and have at
it! It could be anything, from reading
books to staying up late on a certain
online forum?

If that
doesn't appeal to you then try and join
something fun and out of your box like
yoga or kick boxing. There's an endless
amount of things you can do, you just need
to pick, and if you don't like it then try
another.
You're not getting upset for nothing. You
just need to relax and don't put yourself
under a microscope, because no one feels
good when they do that.
