How to talk to my dad about wanting to go on meds

Do my parents need to know I have ocd? Like can I get over it without going to a therapist? Idk how my parents would react. It would make my mom a lot more stressed than she already is, plus idk what my dad would do. I just don’t want to be thought of different than I already am, and I know that I will be if they know I have ocd.

how do I tell my family I have ocd?? . I'm 20, I see them pretty much everyday and it puts a strain on my relationships with them because they have no clue what's going on with me. My mom (amazing mom but... ) can come across cold it's just her personality, she's had a hard life from many external factors and so she doesn't really understand mental illness and how someone can be 'unhappy' when they have a comfortable life. I come from a family of very very strong women and if I told them I feel like they'd just think it was an excuse/attention seeking. They're supportive people but not very understanding in mental health. I already feel very different to my family just based on my personality/values/view of life - this could potentially make me even more of a distance from them no??? how do I even tell someone I have ocd do I just say it???? pls and insight any1 can give soooooooo appreciated thank you

So my mom finally listen to me about the whole having-OCD-thing. I tried insinuating I have it by telling her my symptoms in the simplest way possible until she realized it was probably OCD. I lied to her about the kind of thoughts I had because I was so ashamed of them and was on the verge of crying. Then she told me I shouldn't try getting medication for this because she said she didn't "want this to go on my record" and she doesn't want me to go back to the mental hospital even though it could probably really help me, and I enjoyed the stay I had last time. This just kinda frustrates me to be honest, I just want to get help.
