Tragedy and need serious advice PLEASE help:(!!!!!?

I am so sorry about your Dad. Your Mom will really need lots of hugs now and when your Dad dies. You may want to concentrate on being there for your Mom and studying for your exams. In about a year (yes, I know it sounds like a long time, but it really isn't) you will be in a better position to do a search for your biological parents. At that time your Mom will probably help you with your search.
