I always feel my family is judging me for some reason or the other. How do I get over that?

In life there will always be people that will judge you and no matter what you will do they will continue. What I suggest it that you just take a step back from the situation, and take a minute or 2 to reflect. Are your family really judging you? If so just take deep breath and flush all negative thoughts that you might have about situation and show them that you don't care that they're judging and continue doing what makes you happy.

Try to think otherwise. It's not their intention to judge, maybe they're just worried about you and want you to be better

Maybe confront them about it, or talk about it. Ask them questions you feel you need to move on, or maybe it's just about your self-esteem. As long as you are satisfied with what you do, make sure that other people know that you are happy.
