I am guessing you were not prewarned?
I was in my 20's, when I had my appendix removed and all I remember, was the terrible pain on waking up and wondering what on earth was going on and then, people saying that I had caused a near panic, because they could not wake me up! I realised I was lying in my own blood and then, whisked to a ward and each time I needed to go to the toilet, a curtain was drawn and I was on morphine for most of the time.
It felt like ages, but in fact, I believe I was only in there for 3 days. I was in for 7, with the recent operation and it was SO DIFFERENT. I was on a high most of the time and was flipping blowing kisses at the nurses, as they went to close the door. I had a vague sense of: what the heck am I doing and besides, despite how friendly they were being, they did not blow kisses back and I was mortified. And that was BEFORE going under and someone recently said that it was probably the painkillers I was on, that caused me to go lala hehehehe
I know that it is quite impossible for childhood memories to be all good, because not a single one of us, are perfect, but what people do not appreciate, is what an impact our childhoods have on as as adults.
It is said: get over it; it is the past and this is now. Mmm of course, factually that is true, but we are still the same people, just grown up and so it is inevitable that our childhoods will play a huge part on how we are as adults.
I don't think they even told me I was going to have surgery... I would have freaked out. I always tend to say how horrible people were to me... I was not an easy kid to deal with by any means. I came into this world very confused... It seems I may leave this world still confused.
I was at times impossible to deal with and I feel horrible for it, and I always will but could I help it...
No, I truly don't think so, just like today... Yes, I have matured so much, but I still have situations I cant fit myself into. So many things just sort of short circuit and
internally and I freak out, where as it was just a mess when I was a kid. I wouldn't talk. I was terrified of LIFE in general (still am in some ways).
Communicating how I felt back then was all but impossible. I had no words for the confusion I was dealing with and I was smart enough to notice when I was very young that no one else seemed to be struggling like I was. Its hard to deal with those facts sometimes - even today.
So no, if anything was going to be "bad" they wouldn't tell me until it was happening, or I would have to figure it out afterward on my own.
When I broke my right arm (its was a compound break and my bone came through the skin)... I still get sick thinking about it, and sort of feel sick as I write this... I went out as soon as I saw what happened and woke up later in the hospital. This was right after my tonsil and ear thing...
Then it was healing badly, and this old gruff doctor said (right in front of me), "Well we are going to have to re-break this arm and reset it, its not healing right..." I went out just like I did when I broke it... It was just too much for me to process.
My ASD life has been a weird journey, but I guess its all I actually know, so in the same breath its just a "normal" I never quite fully grasp. : )
