How can u actually start?

For a little bit of context. I am currently 18 Ive been thinking about starting a clothing brand eversince the pandemic but I have never committed to that idea , I've always had a unique style of drawing and designing apart from that how can u actually start? Saw a bunch of old posts from reddit all telling the exact same thing but nobody shares their story. Also I would like to know with what budget can I create some samples for wear. I heard that starting with that and promoting ur product on social media usually works out if u have something thats unique and stands off. Also heard about sites trying out diffrent prints but none of them I actually like , was thinking more of photoshop but i don't know if that makes much of a difference. Please share ur experience below and how u started I would be very interested to hear all about it.
