Hi Marco,
There are many people with anxiety who share your problem.
Is it possible for you to talk to your girlfriend about a short trip away? I
know you have been visiting different places lately. Maybe you could try
somewhere closeby for one night and give yourself permission to return home
if it becomes too difficult. Sometimes knowing you have the option of
leaving can make it easier to stay

Just a thought..
By the way, my daughter called from Bologna yesterday. She loves it and is
looking for employment there for next year.
Take care,
love Meryl
