Just found out I have a daughter. 5 years old. What the fuck do I do?

I just found out yesterday I got a 5 year old daughter. The mom is someone I had a one night stand with 5 years ago and I haven't seen/talked to her since. I always assumed she had my number, but it seems I gave her the wrong number (I was very drunk). She tried for years to get in contact with me but eventually gave up. She ended up finding one of my old friends on fb, and through him she was able to get my new number. <br><br>She contacted me yesterday. Apparently my bio daughter is starting to ask questions about her dad, and apparently she was gonna drag my ass to court to get child support if I didn't start being a dad. <br><br>I'm in shock. Like, I'm actually in shock. I don't know what to think or do or how to feel. I'm just. So. Confused. And I don't know anyone who has went through this before, especially not at 25! I don't know how to be a dad!! <br><br>The mom and daughter are gonna come up this weekend to meet me and see how we get along, apparently. But that's still 6 days from now. How the hell do I prepare for this??? <br><br>Am I even ready to be a father? What the hell am I supposed to do here??? Just show up and be a dad?? WTF? <br><br>I know this is gonna sound awful to parents, but this is not something I ever wanted. I don't think I'm even cut out for this. But at the same time, I know I have to do this. I have to be a dad. Even if I'm not ready, I have to be here for my kid. But how?? And I feel like running away with my head in the sand, ya know? Just ignore the whole thing and pretend I never got the call.<br><br>What the actual hell am I supposed to do?????
