First of all I’m sorry you are going through this difficult situation at work.
Second I can tell you the ending you own life is a very drastic and unnecessary option to this.
Third, you work in a toxic environment and no matter how much money you make it’ll never justify staying.
So what do you do? You leave and take a pay cut. You don’t endure and you most certainly don’t take your own life because of them.
Ending your own life is a permanent solution to a TEMPORARY problem.
Again sorry that your having a rough time. Their are many resources available if you feel uneasy or don’t trust yourself.
