It was listening to family gossip in part (and partly, admittedly a phobia on my part, and a few other practical reasons that had to do with discontinuance of insurance on graduation), that made me choose not to go on medication when I was having my mental health issues a few years ago.
At the time I was living away from home, and basically no support network, no one to check in on me.
I knew that several relatives have gone on various medications in the past. A good psychotherapist will warn you, and you see it as a warning on the bottle, that the first two weeks, as your body adjusts, there might be an increased likelihood of suicidal thoughts or anger or violence.
Therapist I was talking to tried to downplay those issues. Said they happened in very few people.
Thing is, during that two week phase, I've had two relatives succeed in committing suicide, two others attempt it, and one more who had rage issues. So, it would seem there is a predisposition for family members to react that way. The ones that weathered the storm eventually did adjust, so I know that in the long run it can be helpful, but I was afraid to go on medication without any kind of fall-back support network if anything did go wrong.
(Likewise, in three months I was to graduate, and my health insurance to stop until I found a new job that covered it...so then comes trying to figure out how quickly to wean myself off, etc, around that time and it just seemed too complicated).
So, forewarned. I think I made the right decision, based on family history and practical circumstances.
