1) It is not for free, maybe for you but in the end the other health insurance customers are paying for it.

2) You don't and can never turn from a woman into a man and vise versa. You end up being undesirable for straight women and gays (they both want a man with a penis).

3) The "small shot" is not 100% reversible. Ask this your doctor.

4) Your "penis" is made of tissues from your arms to form it into a neo-phalus. You will never have testicles producing sperm cells, you have a female body producing ovum in your ovaries.

You are a woman (judging on your avatar) and you cannot change that. Live with it. Don't treat mental problems with shots or mutilation (chopping out your breasts/vagina).
