What You Need to Know About Mental Illness  

Many people with a mental health disorder don't get treatment. They may think it won't help. Or, they don't recognize the symptoms. Others may not be able to afford treatment. The social stigma of mental illness also stops people from seeking help. This often means worsening symptoms and, in some cases, suicide.

Real illness

Mental illnesses are as real as diseases like heart disease or cancer. But understanding that mental illness isn't a weakness or a character flaw helps people get help.

Some of the more common mental health problems include:

  • Depression

  • Anxiety and panic disorders

  • Post-traumatic stress disorder (PTSD)

  • Bipolar disorder

  • Attention-deficit/hyperactivity disorder (ADHD)

  • Substance abuse

  • Schizophrenia

Mental health problems may be passed down through the family. Or they can arise from abnormal brain chemistry, substance abuse, or in response to traumatic events or an abusive environment. In other words, a mental illness isn't the fault of the person who's suffering.

Signs and symptoms                                             

Learning symptoms of mental illness can help you recognize when you or a loved one need help. Symptoms include:

  • Feeling sad, burned out, or useless. Everyone feels down from time to time. But, if that emotion continues for more than 2 weeks and you also have feelings of guilt and hopelessness, it could mean you're depressed. Severe and persistent symptoms are what distinguish depression from normal sadness and mood changes. Other symptoms of depression are sleep problems, loss of self-esteem, and not enjoying things you once did.

  • Ongoing worries and fears. People who suffer with unrealistic or extreme anxiety and worry about life circumstances could have an anxiety disorder. 

  • Sudden, intense angst, fear, or panic. Heart palpitations, chest pain, feeling smothered, dizziness, trembling, and faintness can be signs of panic disorder.

  • Unexplained physical symptoms. Ongoing physical symptoms, such as headaches, stomachaches, and chronic pain (especially backaches) with no clear cause, can signal emotional upset or stress overload.

  • Chronic fatigue and lack of energy. When your body can't handle emotional overload, it can shut down. Feeling too tired to do the things you used to love can be a sign of emotional distress or depression.

  • Avoiding other people. Spending all your time alone instead of with friends or family could be a sign of stress overload or a social phobia.

Other symptoms of mental health problems include:

  • Ongoing nightmares

  • Flashbacks

  • Dramatic changes in sleep or weight

  • Substance abuse, including alcohol

People who have emotional disorders don't have to suffer without help. It's possible to mend the mind through therapies and support services. Don't be afraid to ask for help. It's a sign of strength, not weakness.
