My mom's is insane!!!?

okay, so she may not be the best mum in the world, but the most logical reason she wants you to try the work again and stand up for yourself, is because she loves you and wants you to do well in your life. She must be a independent strong character which is why she doesn't hug you. But she knows that she is only doing it for your benifit and thats why she understands. Although, this is just my guess. If the situation is worse than I think then please ignore this information. If not then take it as a guideline to your mums personality. I really, really hope this helps..!
