Spinal Block

Okay so I'm really worried about getting my spinal block because my husband can't be in the room with me. I've had two children, the first vaginal & I got an epidural, the second was a csection. With both of my children I had SEVERE anxiety attacks. I don't know why I have this problem as I have never had a fear of needles or anything like that. It is 100% uncontrollable. No matter what I do I freak out, can barely breathe,
Cry, Ect. It takes them very long to do it because of my uncontrollable shaking. My epidural wasn't as bad because they let my husband in there.. But the spinal block was horrible and I just do not know if I can do it.  I really don't know how to go about this again. I want to talk to my doctor about it but he has the habit of acting like all of my fears and worries are completely irrational.
