I went through the stages you are in. I thought that my life was going to be nothing but struggling through a day of work, coming home and dropping into my bed, sleeping as much as I could and being in pain all the time.
It takes time, and I know that's not what you want to hear, but there are solutions to this. There is no "quick cure" or magic pill.
Ask a lot of questions here. Listen to the experienced people, like Mrs D. Bob, and some of the others... take the vitamins, (B-12, etc.) and rest... a lot for now. Get on the anti-depressants and the anti-seizure / pain meds. They will get you through all this.

Unfortunately I lost my job the first year I had PN, the meds and the pain were too much for me to handle. Eventually I got it under control and got back in the saddle. Now I'm working again and even exercising every day. No more canes, no more braces... It can be done! You have to take your time and STRESS IS YOUR ENEMY!!!!!!!!! I can't say that loud enough!

God Bless you, and welcome to the group.
