I feel suicidal because I'm a white male
Why would you feel suicidal just because you're a white male?
Because American society doesn't give a shit about you if you're a white male.
Rather than focusing on race and identity politics as being the cause of your issues, you should seek help and work with a therapist to rid yourself of those suicidal thoughts and become more self-confident. It's easy to fall into a rut and blame things out of your control such as race as the reason for your lot in life. Working with a therapist will allow you to move past those issues constructively.
I don't like psychologists because they're a bunch of anti-white people.
The world is changing and that can feel difficult. But most psychologists are not anti-white; many are white themselves. There are many people who could help you feel better.
