You worry less. Not in general. If you're an anxious person, you'll always have anxiety. But about the specific issue of coming out, which is a pretty big anxiety-inducing issue, even if you don't have anxiety.
I remember when I was 19/20, I would smoke weed with my friends a lot. For the first 10 we'd just laugh, and then after that I would get really deep into my own head, thinking about how I was gay, and how my whole family knew. I'd just sit there going "you're gay, they all know, it's so obvious, and it's so awkward that you know they know and you haven't told them, and she (my mum) probably knows you're out smoking weed, and is probably really worried about you, they know."
The easiest thing is, you can just stop with all the lies. Especially if you live at home and you're in a relationship. That was just the worst. The amount of lies that I used to come up with about staying at my ex's house

I never stayed at friend's houses and then all of a sudden I was staying at a different friend's house 4-5 nights a week, and then a couple of months later it just stopped. So obvious.
