I'll quote the lede from the abstract so people know what they are clicking on:

Instead of curing depression, popular antidepressants may induce a biological vulnerability making people more likely to become depressed in the future.

Nobody currently taking antidepressants should stop them without very careful planning and consideration of whether they should and how, but the same very strong consideration should be given before starting them for long term use, too (with a professional ideally, which I am not).
