I think it makes sense, really. I mean, you're now on testosterone, so it's this massive thing that's going to give you changes that you're going to feel awesome about. But it happens slowly, so when you're in the beginning stages, it feels bad to know that you're finally on it, but so far you're not experiencing big enough changes to help. So I think time is the key, here. Try to remind yourself that every day that goes by, you'll be experiencing more changes. Small, of course, but those small changes add up. Maybe also you can try to work out a bit, maybe it'll give you more confidence in the meantime, because you said you're quite petite?
