What to do AFTER severe constipation?

Went to ER in agony 4 days of ping nothing and after 1 enema, a HUGE enema (couldn't keep either in) and a drinkable laxative which they swore would work, two days later a little bit slimed out. I haven't eaten in 5 days and am scared to eat something. I've lost all urinary control and keep pissing on myself - Im scared to get into bed in case I make a mess. Do I have to keep taking laxatives at this point or can I eat fruit and water or something??
