Feeling angry still after being told told to wait while i was in labour, how do i move past this?

SORRY THIS IS GONNA BE LONG.....I went into labour with my second child and being experienced I did most of the labour at home, when my contractions were less than 5 apart i called the hospital to let them know I was on my way. to which they replied we are too busy, its not safe for you to come here now there is no one to look after you??? I pleaded with them and they insisted that if i came in no one could look after me as it was too busy already, they told me to take a shower and have some panadol, even though i said i had done all those things and my waters had broke almost 24 hours ago, they said stay at home, desperate i hung up the phone and travelled to the hopspital where i spoke through an intercom and said i was in labour and in severe pain, they told me to take a seat and wait? no one come out to me and after 20minutes I became really frightened i was going to have the baby out in the corridor? I was even vomitting on the floor as i had no where else too, in the hospital corridor.... so humiliating. My husband buzzed numerous times to try and get someone and they just kept saying she has to wait? finally about 40 after id arrived someone came out and to my dismay called in another lady who was not in Labour!!!! thankfully she knew my desparation and signalled for me to go in, instead of her. when I got into the room I told them I was not "sarah" ...they stilled seemed mad and at this point i thought they were going to kick me out again. the nurse said oh i will go get a midwife....and by the time she came back had all my clothes off pleading with her to let me push, as i felt i needed to but was scared also that maybe i shouldnt yet. without her even examining me, she said yes just push and My beautifull son was born shortly after a few pushes. He was born "flat" and needed a little help to breathe but was fine after 5 minutes. I dread to think what would have happened if i stayed at home like they said or didnt sneak in under someone elses identity. 2 days after my birth I also discovered a tear that they had missed and i needed to be stiched up 2 DAYS later, no one had checked me, I also dread to think what would have happened if i didnt notice things werent right down there. Oh and when I did go to get stitched up they didnt use and any local anaestetic and it Hurt like hell while they stitched. There were a few other things that also went wrong but I cant go on forever?? My baby is nearly 3 months and this whole thing still plays on my mind and upsets me. I know i am lucky because my son is fine and so am I but I wrote a letter of compaint to the hospital, but of coarse they dont care and never got back to me. Has this happened to anyone else, if so How did you move on from it. I dont want it to happen to anyone else, how can i get the hospital to prevent this agian!!!
