Hi, Torilusk!
Welcome to Susan's.
Every person reacts to HRT differently. Hence the common expression "YMMV" (Your mileage may vary).
Breast tenderness indicates growth, and will typically continue as long as they are growing, which could be two or three years. Growth and pain tend to come in cycles. You might find that a sports bra helps with the pain, and it might help with concealment, too. Some of them are easily mistaken for a tank top if seen through clothes.
The effects on hair, skin and smell might not be your imagination. THose effects can happen quite quickly after you start HRT.
If you stop, the growth will stop, and there might be a little bit of shrinkage, but your breasts won't go away.
