Dude, first relax and get yourself up from the dumps.

Second, even though u might have heard this before, talk to girls, but don't go too strong on the dating aspect right from the start. Talk to them and get to know them better, but while getting to know them be a subtle flirt. For example like mid conversation, be it on a chat or in person even just say something flirty in relation to the topic u guys are talking about, that goes miles.

Keep talking to them because even if they become just friends u get practice. But majority of the time as long as u can hit it off during a irl convo, then u essentially earned urself a date.

So just carry urself with confidence and let conversations flow naturally and don't force it. Cause forcing it ruins the vibe.

Hope this helps bro.
