Describe what exactly you mean by people judging you. Why do you feel that others are judging you?

Talk to your school councillor. Talk to your father since he seems to understand.
Tell him about your depression and social anxiety. You may need to see a psychiatrist
to see if medication could help. And see an outside therapist possibly. Look for
library books on how to talk to other people and socializing.

I'm going through what you're going through. I feel like I'm on the verge of having a panic attack every time I'm in public. I feel like everyones eyes are glued to me and judging me. I am constantly worrying and thinking of any possible judgment anyone could make for me. If you need someone relatable to talk to... I'm here.

I'm here. You are not alone.
I know what that feels like. Ignore your mom. I know its hard advice to follow, but by her laughing at you all she is doing is hurting you and tearing you down, when she should be helping you. That doesn't mean she is a bad mom, but she doesn't sound like she really understands how hard and scary these feelings can be. It sounds like your dad is trying to be helpful, but maybe not how you need him to be. I'm glad you wrote here and are reaching out for some connection. That means you can reach out. Remind yourself of the little things you are doing, it helps get out from the pull of the thoughts "I can't". You Can Do This.
Message me anytime, I've been where you are and knowing there are people who support you was the most helpful thing for me.
Sending you lots of Love and Positivity.

My dear,

Jesus said 'Those who are strong do not need a physician, but those who are ill do." Mark 2:17. Please see a loving professional to help you develop coping skills. These skills are important to help you manage your many years to come.

I feel you my mom thinks that I'm making up my social anxiety to be dramatic

Sometimes I also get stuck away from the world for awhile because of social anxiety. I struggle a lot to make calls (which I very seldom do), go into stores, or really leave my house, although it's not very bad if I don't have to go in anyplace. Social anxiety is downright terrible. We've got your back, though, and we get it! It's sad there are so many people who do not.

The thing with people who don't have these issues is that they underestimate how severe it is. It's the most throat grabbing, cheat clenching, stomach wrenching feeling ever.

I'm sorry you are going through this but please know you have support on this site! This is up to you whether or not you'd like to try it, but maybe one day when you're feeling up to it, go out for a jog on a trail, park, or area when not a lot of people are around -maybe very early early morning and bring your music to listen to as you're jogging. Exercise is a great stress relief in general and as you pass by one person, choose to notice them and notice they're concentrating on their own individual task, and as you run into maybe another person, you are exposing yourself -but to your comfort on how many people you can be around. If another person gets too bad choose another route that's empty and call it a break. Overall I wish you the best and stay strong!

I know how you feel. I am scary to go outside. Some people do make fun of me. They just do not understand how we feel. They have all me lazy. I am not.
