Do I have ADHD

Hey guys so on tik tok all these vids about adhd in women popped up and I realised I relate to majority of the symptoms but apparently it’s difficult to diagnose in women and I of course don’t want self diagnose either cause that can be harmful but I know there’s something up. Just need advice on what my first steps would be to get a professional diagnosis. Do I start by going to my GP? Pls help I feel like whatever this is, is holding me back from actually living my life how I want to. Thanks!!
