Insecure

I’ve really been trying hard to find a girlfriend lately. I’ve been super out there and talkative when I got out with my friends but I’m also super oblivious and shy when it comes to someone I find interest in. Not to mention I’m super insecure about how I look. I’m a lesbian born female but I would say I look more like a dude. I’m super tall 6ft have broad shoulders, dark skinned. I’ve been mistaken for a guy so that has just dropped my confidence at this point I’m at a loss. Any suggestions?
