G'day. Welcome. It really won't take you long, although there are a few abbreviations which took me a while to learn (such as Residential Treatment Center (RTC), which we don't have in Australia).
When you get a chance, do a sig so we can have always at hand, a summary of you and your family so we can always make sure any suggestions are relevant to you. Also, do make sure you keep your confidential details just that - confidential. It's another reason for the acronyms - this way you can vent about unnamed teachers, doctors, the Board of Education, whoever - without fear of reprisals, because they will have no way to connect you to who you really are. A very necessary precaution, for a lot of us.
