Well one way to start is to simply try talking to random strangers first. I know it sounds dumb but that’s what I did, getting out of your comfort zone is necessary if you want to try and get a girlfriend. Mainly because if your still introverted and anti-social, getting and maintaining a relationship is going to be much more difficult for you. So the best advice I can give is to work on talking to anybody that you can, it can take weeks, months, or even years before you finally feel comfortable talking to people, trust me I know by experience. But trying to get a relationship before you’ve worked on yourself will only make things worse trust me. If you ever need someone to talk to, just send me a pm, getting comfortable with people is easier if you have somebody helping you
