A lot of T's are not good with SI... keep looking... they are out there! Please let us support you in any way we can. First and formost are they bad enough that you need to go to the ER or get help right away? if there is even a hint of question go get them looked at. This may be a stupid question and my intent is not to offend or insult but... do you know at least basic first aide? Like beyond what mom did when you were a kid but not what a Dr would know either. It may be beneficial to take a basic first aide course there are a ton out there. At least enough to know how to manage the injuries until you can get to a Dr? Right now what is done is done and needs to be treated to make sure it heals propperly and does not get worse. Also do you have the propper first aide stuff to take care of it?
I know that it is easier said than done but forgive yourself and start anew... stewing over what is already done would only create more stress and you don't need that now. Focus on the road ahead, self care, wound care and how to keep yourself safe until you can get the help you need and want.
Usual disclaimer... I am just opinionated... I am not a Dr or a T... my opinion is only that... an outside, observers opinion.
