Welcome to our forum. I am sorry to hear about your accident. I recently experienced an "incident" myself. Now months later, I have mixed feelings about it. I am not sure how advanced your depression is but I will tell you that depression will absolutely dominate one day and be dormant the next, it is awful.
As far as your pain, if they did any type of compressions you may have a bruised rib or chipped zyphoid process (Sternum) If that is the case, you will be sore for a while but no damage is done, another thing is sometimes they do what we call a "sternal rub" which means that you were unresponsive so they rub you breast bone aggressively to try to get any response from you. That will really hurt for a while but will not cause any damage.
You should really have no pain regarding the procedure. If any thing you may have some rawness of your throat lining like a sore throat. This is from the ipecac (charcoal syrup) they used to induce vomiting, plus you have a breathing tube, this could also make your throat sore.
I had muscle wasting with my event that will have side effects the rest of my life, as I am lucky that I can even walk normal. In fact when I feel muscle weakness it brings back memories of that day and sometimes it serves as a reminder of how silly my actions were.
You will have rough days but we are here.
My prayers are with you.
Of all the moments in my life, you were always there somewhere. Once as a wish. Once as a blessing. And now as the greatest loss I'll ever experience."

If I could have one wish, it would just be this, I could take you to my soul and show you all the love there is."
