For MOST people. But some people have very resistant depression. Some have dysthymia. Some end up getting shock treatments or transcranial magnetic therapy. Many find relief from meds after trying different ones. Some struggle, never see a light at the end of a tunnel and kill themselves. I am just saying it isn’t as simple as saying, “Depression is a very treatable condition.” In my mind that sounds like telling someone they can get over it if they just “buck up”. Makes me wince.
Depending on why they are depressed also plays a part. I had developed a severe situational depression in reaction to severe ongoing pain. I am very lucky I was finally able to find the cause of the pain and eventually get it fixed. It went on for almost 10 years. Constant unrelenting pain in my jaw that effected my ability to eat, smile, talk, could barely open my mouth, hurt to have things touch my face, including the phone. May sound terrible but my ex husband committing suicide during that period of time kept part of me going; I knew I could not do that to my (grown) children. Plus guess I am lucky I am bullheaded as all get out - I KNEW something was very wrong and no matter what I was told or how I was treated, knew I was not crazy! I have now had artificial jaw joint implants bilaterally for 11 years this coming June. Pain went away almost immediately (sure, had postop pain but that’s different)! My depression took awhile, but it did improve. I was one of the lucky ones.
