You have now several options to deal with the pressure problem:
Increase your resilience toward stress. Structuring your tasks can help, as can set clear borders between work/non-work. Your company is not everything - and I say this as someone who has a burnout history, so I know it's pretty hard to really absorb that. Dev.to is a great resource for tips about mental health in dev. Having non-dev hobbies/friends/social contacts definitely helps, too. And having enough sleep (I'm guilty on this one, too, but working on it)
Decrease the amount of workload/stress you're exposed to. This can happen through speaking about your issues with your manager, but again this requires a high amount of trust and a competent leader. It can happen through requesting clear prioritization and making the actual effort needed to solve a task more transparent.
If neither helps, thinking about changing your workplace might be a good option, too. You're too valuable to get burned by careless managers/company culture. Again: I have some personal experience in that area :)
If you have thoughts like "but I'm too bad/inexperienced to ever find a job somewhere outside my company" I would highly encourage you to start searching for a job pretty soon. Chances are very high that your company actively works on such a mean and toxic culture to prevent you from leaving. Good managers/leaders will encourage you to thrive and help you in growing personally. Things will not get better, but you will continue to suffer.
For further actions, you may consider blocking this person and/or reporting abuse
