I can understand your situation and that too after losing your mother and living in others house. People around us will continue to be judgmental as they have their own perceptions. You have gone through many challenges that has made you strong enough to face the world.  Lend deaf ears to what others think or talk about you, as far as you keep moving in your life by academically qualifying getting into a good job and self support. There are amazing strengths within you that you need to identify and feel good about yourself than worrying about setbacks.  Do a self-assessment to discover your strengths and skills. Also list out limitations and work towards converting them into strengths. Your school/college may have Counsellors, approach them for help.
