I've been in therapy off and on for 19 years.

Current T: 15 months (age 31)
T7: 2 years (age 22)
T6: 7 months (age 22)
T5: 4 years (age 18)
T4: 2 weeks (age 18)
T3: 2 months (age 14)
T2: Few months (age 13)
T1: Few months (age 13)

Current T, T5, and T3 are all good Ts. T1, I don't remember her. The rest were bad Ts for me.
