I felt bad when reading your post so I wanted to reply. Even if it's not helpful, know that someone does care, even though I do not know you personally.

Are there any welfare programs in your area? I know being on welfare may not sound like a great thing, but being homeless isn't good either. Welfare programs can also assist people with getting jobs too.

It's great that you went to school & achieved those high grades! It's a shame you are having a difficult time finding employment. I know you feel so rejected right now, but keep your head up & keep trying. I personally know intelligent, good hearted people who have been rejected for jobs over and over again. Sometimes a person may be over qualified, sometimes under qualified.

I do not know what the deal is with these employers, but I hope you make it to med school. As hard as it is to keep getting rejected, keep trying. Don't lose hope. Your future depends on it, I hope you get hired soon.
