"Discharged too early"

I am booked in for 4 week drainage of my stomach. I received a letter to come in, but when I did there was no bed for me. I was put in a big room with lots of people. I waited there the whole day before I was given a bed.

I had the drainage done at night time - 10 litres was drained. The night nurse was supposed to take the needle out at 4 am, but she came and took it out at 8 am.

I felt extremely weak and when the doctor came to see me I asked if I could stay longer and he said yes. But as soon as he left the nurse came in and told me I could get dressed and go home. I was so weak, I could hardly get dressed. They could have at least got the orderly to come and walk with me down the corridor so I could find my feet before, just sending me home. When I went to leave, I believe they thought I was going to another hospital. The orderly who walked me out was very pleasant. 

I have to have this done again in another 4 weeks and I'm really worried. You have to have this done to really understand. I feel very weak. I think they really botched up.
