How can I make new girl friends ??

I am 25 years old and lately I’ve been so lonely. I recently got Out of a relationship. I spent a lot of time with my ex when we were together. We did everything together.

I lost touch with some of my girl friends from high school. We still talk and occasionally hang out but they all have their own lives and I know I can’t hang out with them all the time.

I feel like I don’t have a best friend. I don’t have a girl that I can talk to whenever I want to gossip or just talk about my day.

I don’t know where I can make new friends. I haven’t made a new friend since high school. I just feel like a loser.

Any advice ??
