I'm so sorry that you are in so much pain and feeling the way you are feeling.
Are you taking your anti depressants? I'm sure they can help you, but it does take time to build up a level that will help you.
If you are taking them and they are not helping you, you really do need to talk with your doctor.
You also really need to express your feelings to your family.
I know it is hard to do, I've been there myself, and it is important. Your family is hurting as well, and they are feeling terrible that they can't help you and relieve your pain.
Just talking to your family can make all the difference in the world. When they understand how you feel, it makes it easier to deal with.
As for your surgery. If you have had a second opinion that says the surgery will not help your pain, because of the way the doctor is doing the surgery, then you really shouldn't have the surgery done that way.
You should get a third opinion first as to what is the best way to do surgery and access your nerves.
You have 2 different opinions as to what way the surgery should be done and info about the nerves.
One may be correct, but you don't know which one is. You need another opinion as to which way to go.
Please try and get a third opinion before having the surgery. There is no reason to have surgery again if it is not going to help you.
Please get to see your GP and let him/her know how you are feeling. Take a family member with you or a friend.
Good luck
