See myself as a somewhat confident person, don't really have an issue with talking to strangers, but when talking to girls I find myself at a loss of words and act kind of awkward/not myself at all. After talking to a girl that I just met (Just happened 20 minutes ago in uni lecture), and if it goes not as expected I won't have the courage to do it again for a while. People on here say practice and you'll get better, sure it sounds good but I don't feel like I am getting better when I do and feel worse off.

How can I change my mindset on this? First post in here but have learnt a thing or two from this sub so thanks all.
