I don't see how a birth can be comparied to going to a dentist. Birth isn't about pain or anxiety. You're in a different state of mind when you're in labour.

I have had very bad experiences in that past with dentists which is why i have not seen one in nearly 6 years. I haven't been able to control my anxiety as yet. So if i can''t use the gas then i am just going to have to wait because the stress will not be good for the baby either. Unless there is something else i can take?
