It looks like 10-24 age range saw an increase since 2010. There's a small dip for 25-44 in 2018, but it looks to be trending back up)

Rises in all age groups except 45-74 (boomers).
So it looks like, at best, trans medical care has done jack all for the overall US suicide rate, and is likely making it worse.
