you'll be sterilised by the treatment
you'll become somewhat confused, and more emotional, as your male brain is forced into operating with a completely incorrect hormonal profile
this can lead to an exacerbation of mental illness, including depression and so on—look at the symptoms of testosterone deficiency in men to get an idea, although note this doesn't necessarily cover the symptoms of an excess of synthetic oestrogens
(i.e. increased risk of certain cancers, blood clots, cardiovascular issues, 'liver damage' or cholestatic hepatotoxicity, emergence of mood disorders, exacerbation of depression and anxiety, reduced or absent libido, etc.)
in your confusion, you might be groomed by neomarxists, who will use you to agitate against your society and people, with demands of special privileges and rights
they'll make you feel like you have a family, and a community—they typically operate by grooming young people with poor home lives, or few friends—but will drop you the second you stop being useful to them
whatever you do, do NOT opt to have them chop off your penis or testes—whilst the sterilisation is permanent, retaining your genitals gives you an escape route when you realise it's not actually possible to become a woman, with either current or near-future technology
this decision will hopefully preventing you feeling suicide is the only way out
