Mental turmoil

According to Ivan Mak Wing-chit, chairman of the Public Awareness Committee at the Hong Kong College of Psychiatrists who has followed up on survivors of Severe Acute Respiratory Syndrome, life-threatening illnesses cannot simply be brushed off.

"It's a trauma. Ordinary life stresses can be handled easily, but it won't be like that for people with COVID-19," he said, adding that some patients never fully recover from such an illness because of the heavy emotional scars.

Patients have some initial mental disturbance after a sudden, traumatic emergency. That's "acute stress reaction", he said, noting that the symptoms are very similar to those of post-traumatic stress disorder.

However, acute stress usually only lasts a couple of weeks, while PTSD can last for years or even the rest of a person's life.

Acute stress comes in the first month after a trauma, followed by intense fear and emotional distress. The illness is the primary trigger, but there can be others, and factors such as compulsory quarantine, isolation and absence of social support when the patient needs treatment in seclusion can exacerbate problems.

Deficient medical care can also be a factor, as in the present situation, as patients realize doctors have limited resources to help because the disease is new to them and they have to make "best guesses" for treatment, Mak said.

May Lam, a Hong Kong psychiatrist, said personality can also play a role. For example, some people are prone to anxiety and have a stronger acute stress reaction than others. Vulnerable people often have a "high trait anxiety" personality, which means they tend to complain about fears, worries and other anxieties in situations where most people would barely react.

Mak said anxiety means patients are likely to fixate on "catastrophic thoughts" and look for the worst. Because they lean toward the negative, they tend to amplify their fears or dwell on the source of their stress. As their mood worsens, so does the intensity of catastrophic thoughts, creating a vicious cycle.

Finally, stress can be overwhelming. "There's a balance inside us: On the negative side are insecurity and even the threat of loss of life, and on the positive side is the person's ability to cope and benefit from the support of others," Mak said.

If someone with stress feels the support is inadequate, whether from family members, who cannot visit or talk to them, or doctors who are uncertain about the treatment, the balance tips toward the negative. Then, stress really takes hold.

Despite Sun's melancholic, resigned attitude, she reacted well to treatment, which she attributes to her sound general health.

On Feb 21, her nucleic acid tests were negative, so she was discharged from the hospital. She had to remain isolated for 14 days before going home, so she was taken to a designated hotel.

She went home on March 5. The time leading up to that moment was an emotional roller coaster, especially as she had to have a final nucleic acid test.

"I waited for the result for most of the day. I fidgeted around my room. I started betting that the result would be positive. I thought being sent back to the hospital would be my death sentence. I cried my eyes out," she recalled.

"At about 3:30 pm, the result came. I heaved a long sigh of relief. I felt so good."

She said she had won the hardest fight of her life. "I thank my daughter for hauling me back from death's door. I gave her life 43 years ago, and she saved my life," she said.

Now, Sun cherishes life more than ever. "I'll take good care of my husband, my life companion," she said.
