My wife suffered a combination of depression and PTSD caused by a very bad childhood since basically middle school.
Under the stress of a newborn child it started to escalate to dangerous levels so she seeked help. After many failed therapy attempts she landed on Sertraline, which caused her symptoms to almost completely vanish and had only very mild side effects.
In the beginning she could not believe that neurotypical people feel like that all the time because she could not even remember a time anymore without depression and anxiety.
It fundamentally changed her and after 2 years of taking it, for the first time since she can remember, she is worried about the future and looking forward to it instead of hoping that she may die soon.
Talk to your doctor, get good advice, but don't be too afraid to try medication because it could potentially vastly improve your quality of life.
