In some cases, you may be able to effectively manage your condition on your own. But depending on the severity of your struggles, seeking professional help may be your best or only option. Even if you have a minor ailment, the pressures of your life could cause your thoughts, feelings and actions to spiral out of control.
In terms of time and money, you must ask yourself how much your happiness is worth to you? If you suffered from a physical illness, you probably would not second-guess your need to see a doctor. Your mental health should be no different. The earlier you begin treatment, the better your chances are for recovery and feeling like yourself again.
