Hola Nerida,
I'm new here, too. I also know what it's like for you. I think that all of us here know what you're feeling--at least to a certain extent. I think, like me, you'll find a lot of comfort, support, and good ideas to try by reading through the messages posted. Other than seeing a doctor for the obvious physical symptoms, have you tried any type of relaxation or deep breathing?
Good luck to you!
