I have to declare first that I have never gottenhad a mental illness, but I can givshare some thoughts about this topic.

I feel like "had" is better than "gotten" here since to me, "getting" an illness is more related to getting infected with an illness that spread from someone else (a cold, the flu, etc.) while "having" an illness is more suitable for things that develop over time and are not caught from other people (autoimmune diseases, mental illness, etc.). Other native speakers might disagree.

We can see many people havdeveloping mental problems at anyregardless of gender and at any age.

It's both really sad for them and us.

I am not a medical worker, so I don't really know the reason whichwhat causeds these problems, but I guess if it's not caused by the brain tissues, it is mostly caused by people's mentality.

If pPeople who are open minded, kind, friendly and generous, they hardly seem to getdevelop mental illness, otherwise, they are easy toes. Other people seem to develop them easily.

So, the best way to avoid gettdeveloping a mental illness is to build a strongyour mental power and be open -minded to everything.

Additionally, giving is always beings more happierness than taking, and I think it's another good method to keep fromway to avoid mental illness.
