And while we’re at the subject of mental illness:
There is nothing shameful about it, nothing. It’s just a disbalance in your brain, one that is usually genetic, and if you think this is shameful then you would surely call MS or ALS or cancer shameful because there’s nothing you can do about those either and there’s no way to handle it by yourself.
Unless you think you can mind-over-matter a serious illness.
The only thing that will help you in a clinical depression or ANY other case of mental illness is asking for help, or accepting it when it is offered.
Do NOT keep it a secret.
Do NOT put off going to the doctor.
