New to self cathing

I have been told that I have to start self cathing, Not Happy At All.  I was told I have Neurogenic bladder. I have been able to not have to do this for 5 years.  I'm 35 and this with everything else is so overwhelming. I was told that they could put a cath in upper pubic or through belly button.  Not happening. I will fight them tooth and nail for this not to happen.  My husband thank GOD is great and very helpful, I don't know what I would do without him.
