as others have said, you don't have to hate your body to be trans! getting a therapist would definitely be a step in the right direction, but not a requirement. they could help you learn more about who you are and who you want to become!
for some people, dysphoria can feel suffocating, like it's enveloping them - BUT everyone experiences dysphoria differently, in different frequencies and in different levels of severity. some people feel mild dysphoria on occasion, some people feel severe dysphoria constantly, some people get bursts of awful dysphoria from time to time.. everyone is different. regardless of your feelings towards your body, if you feel like a boy, you are a boy.
