For me it helps. But it's one of those "works on my machine" type things. I beleive it's a combination of physical exertion+emptying your mind. In ancient times people did manual labor and prayed or meditated. I beleive the focus on the workout and free your mind of external shit and internal thoughts is the key thing. That's why I leave my phone at the locker when lifting and advise people to do so.
An hour or so of physical activity every other day or so, where you're emptying your mind from sad thoughts and outside shit that fucks you up is the key, imho, to summarize.
Hope this helps, hope you get better.
