How will it be without my leg?

Dear Simon,

I am 25, just cleared campus and thought I had everything going for me until I was told my leg would have to be amputated from the knee downwards. I had been feeling a slight pain on my little toe and when I went to hospital, it was established that it would have to be amputated. When I sought a second opinion, the doctor said they would need to amputate from the ankle. When I sought a third opinion, I was told it would be cut from the knee downwards. I think I am done with this life. Can’t imagine living without a leg. I urgently need your help.  Please advise…
