Welcome to the community. It's a great first step.
Approaching has more to do with mentality than the actual approach. It really sums up to pushing through your barriers and realize that rejection is NOT the worst thing that can happen when approaching a woman. (You could be saying Hello to her boyfriends fist.) Lol no, but seriously it's mostly mental.
For now just focus on being social and having fun. Build your own social circle of people that you can go out with and I wouldn't worry too much about getting phone numbers, let alone getting laid, for right now. Hope this helps and we are here for ya buddy.
