I haven't read your previous posts to know whether you've been diagnosed with PTSD. I'm not personally a very big proponent of medication, but I do think it has some merit when it comes to PTSD specifically (I can't to speak mental health conditions in general). It is used to reset serotonin levels, which have gotten out of wack during the fight flight freeze cycle that your body is stuck in. It doesn't mean that there aren't alternative methods that can work, but depending on the severity of your symptoms, your finances, and your other life priorities (needing to work), this may or may be something you feel you can pursue.
Edited to add: I agree with you that medication does not "fix" the source of the issue; that's what therapy and other treatments are for. For me, I am hoping that it will allow me to actually get to the source of the problem in therapy by better managing my symptoms. I have no intention of staying on this stuff for life, but I am trying it out for a short period of time (long enough to trial and error a few different combinations and long enough to actually have it take affect).
