"lack of attention"

i had to take my disabled son to sandwell hospital on the 18/09/14 . he fell down the stairs. he suffers mental health problems and has attempted suicide several times and self harms. he is absolutely terriified of hospitals and this was told to them. i booked him in approx 9.45 am and we were still there at 4.00 pm . the nurse gave him 2 co codomol. thats the only treatment really that my son got apart from a blood test. i asked how much longer before my son was seen due to his fear etc and was told theyre busy so just wait. they wasnt that busy and i wasnt trying to push the queue as such. he was seen by a doctor after 12.30 pm approx. the doctor was nice to him though. he did try to sort out the mental health team. i had to leave my son to fetch my 3 little grandchildren from school and i asked the nurses to keep check on my son and not let him leave although he couldnt as he could hardly walk. when i went back 1 hour later i found my son rocking from side to side on the bed in the cubicle, holding his head and crying, literally petrified.he was shaking so bad. he was checked on only once. my little children burst into tears seeing their daddy in this state. i ran to the nurses and told them his condition and that i was taking him out immediately. i was broken hearted at the way my son was left. he had been waiting for the so called rapid response mental health team. they never showed up. the doctor had called them a couple of times but they never came. they should be called rapid no response. i had to struggle with my son on his crutches, holding him up, trying to calm the children . i asked for a wheelchair to get him to car but none was given. a lovely nurse walked behind though and asked if we were okay. i told them i will be making a complaint, but my son didnt want me to complain about the nurses and lack of attention but i have written a letter about what happened and the so called rapid no response. my partner is a dual qualified registered A+E and mental health staff nurse and he was disgusted at the way my son was treated. he used to work at sandwell hospital years ago. this hospital is useless now.
