Write a thesis statement about mental health

In order to start of a thesis statement about mental health, you’ll need to think of a question. For example, “Many people wonder what the main cause of depression is” and then after that you should answer the question. Here’s my example:

Many people wonder what the main cause of depression is. According to studies, there’s servers factors which are the main causes such as abuse, death or a loss, major events and other personal problems.

And that’s a thesis. ^

A. parasitei'm not possitive if that's right sorry if that's wrong it seems like that would be the answer though.
