The child is not going to school, refuses to communicate, is grumpy, and is avoiding you. This makes you anxious and worried. I have the following suggestions:
If you think your child has a mental illness, go to a psychiatric hospital. Be honest with the doctor. If the doctor says to take medicine or go to a hospital, do it. Do not stop taking the medicine without permission.
Second, children who hate their parents and cannot communicate with them can drive people crazy. These kinds of family relationships are not created overnight, and parents need to make changes now.
(1) Parents should try to get along. They should not yell at each other or blame each other. They should discuss everything together and not blame each other.
(2) Don't regret your past mistakes as a parent. It's useless, and it makes your child confused.
(3) You must take care of your child.
(4) Don't punish or intimidate your child.
Don't neglect your children or let them run wild. It's irresponsible.
Don't make your child feel guilty.
(7) Think differently. Imagine you are the child. What do you want? What do you dislike about your parents?
The situation is bad, but it can change. Parents must think, stay calm, and not panic. Apologize to your child for past mistakes, even small ones.
Third, talk to the teacher and arrange for school enrollment if your child needs to be suspended or go on leave.
Fourth, don't share information about your child's situation with relatives. Give him a quiet space so he's not disturbed.
The pandemic is three years old, and there are economic problems at home and abroad. Parents work hard to make a living, and their children are a burden. Life is difficult for adults! I have given you many "don'ts," which are also restrictions and requirements for you as parents.
It's hard to do this! Your child is 14, which is a tough age for them. This is a chance for you to fix things. It won't happen overnight, so be patient.

I can see how deeply concerned you are for your son's wellbeing. It sounds like he's going through a very tough time and might be feeling overwhelmed or misunderstood. Have you considered seeking professional help, like a counselor or a psychologist who specializes in adolescents? They could provide the support and guidance he needs to express his feelings in a healthier way.
It must be heartbreaking to watch your child withdraw from family and school life. I wonder if there's a specific interest or hobby that he used to enjoy or might still have a passion for. Engaging him in something he loves could be a gentle way to reconnect and show him that you care about what matters to him.
The situation with the 'fairy godmother' seems to have had a significant impact on your son. Perhaps acknowledging the mistake openly and sincerely apologizing for the decision might help rebuild some trust. Letting him know that you're willing to listen without judgment could be a step toward mending the relationship.
Your son's reaction suggests that he may feel a lack of control over his own life. Giving him choices, even small ones, might help him feel more empowered. For example, allowing him to choose when and how to seek help, or deciding on activities that could bring him out of isolation gradually.
It's clear that your son is struggling, and it's important not to take his hostility personally. Building a bridge to communication will likely take time and patience. Maybe writing a letter to him expressing your concerns and love, without expectations for an immediate response, could be a less intimidating way for him to hear your thoughts.
