My side of what i think why i needed ankle surgery versus the doctors reason

Ok so on the 22 of may when I went to the orthopedic he told me to take off my shoes braces and socks so he could look at my feet I complied with no fight this time because I went alone.  As he was touching and poking my feet he says your right foot is soooooooo swollen I need an xray and the results came back as he thought I needed ankle surgery on my right foot because my ankle was collapsed. He told me I should of got it when I was ten but it was'nt available for me he said my ankle was always collapsed but i had my own opinion.  I told him I was walking ok before but I think it happened two days before the doctor visit.  I was at Jessicas house just hanging out with her and goofing off.  then at ten at night I decided to go home shelives well it takes an hour and fifteen minutes to walk home from her house.  I had my braces on I was feeling ok until I was at neighborhood and commack road thats when i heard a pop I was five minutes a way from home when my right foot gave out.  I saw Alicia Billy and his wife Emily.  I overheard billy saysomething to his wife and sister and Alicia went home with emily while billy came closer to me he asked me a bunch of questions and asked if i was alright why am i walking in the dark alone and why am i limping.  Am I in pain I told him I was fine I limped five more steps then I collapsed.  Billy came closer saying dont lie to me you just fell Im carrying you home.  and he did I hated it I knew I could get back up and walk again. when we got to my house i told him thanks and please put me down he says when we get to your bedroom i said i could walk there myself he says im worried if you fall again.  i said i wont and he says nope.  we got to my bedroom he placed me on my bed and he left.  I took off my shoes braces and socks to find a swollen right foot.  The next day billy calls me up asking if i was wearing my braces that night walking home I said yes his sister who I am friends with also has cerebral palsy mild like mine also falls at times but i always had my balance never lost it in three years.  thats how i thought my ankle collapsed.  The doctor says my ankle had always been collapsed and its not my fault so i got the surgery on june 4 and next year im getting it on my left foot.  Today I start physical therapy to learn how to walk on the cast Im so scared. Yesterday I was going to take a sponge bath Brielle told me to take a shower I said no I rather take a sponge bath she says my cast is waterproof but i refuse the showerchair.  I know its waterproof I cant put pressure on it yet it hurts.  but today i got to the therepist is gonna make me.
