I cannot study due to being stuck in a situation of financial crises, family stress and and inner turmoil of not able to tell who I am due to homophobic society. Any tips that can help me?

What do I do when my parents are mad at me about my math grades in school?

I feel like my parents lost hope in me because I don't do anything in school. It makes me feel depressed because I hate to disappoint them. Do they still care about me?

My best friend who I've known since 1st grade is being overly mean to a friend I met in 6 grade. After she got in a quarrel with another friend of ours. I've tried to fix it. What can I do please?
