Are you able to speak with a therapist? Do those big feelings seem to appear randomly or due to consistent behavioral triggers?
Do you have any specific trauma from family or bullies? If so, you should look into a "trauma -informed" therapist.
Note: If this is your first time meeting with a therapist, know that it's a match-making process. Before jumping into your personal history, determine if you and the therapist can communicate well, and you feel comfortable to communicate.
A good therapist will likely not tell you, "here's what's wrong with you. Go sort it out." The goal will be to understand how your brain and body respond to your environment. It's a learning process.
I hear you. The bigger issue is that companies are now giving technical interviews that previously would be a 2 week long in-house project, but now demand "proficient candidates" complete within 3-4 hours. They compromise by saying, "you can use any chatbot you want!"
My interpretation is that the market wants people to know enough about what they're doing to both build AND fix entire projects with chatbots. That said, many organizations are only selecting for candidates who do the former quickly...
