Advice please ?

Really I just feel like venting, give me some advice please lol so I will be turning 24 shortly, the past 5 years of my life I was in a relationship with a guy who was not good for me and held me back a lot, I went out with him/we went on a date maybe a total of 15 times in those 5years.... We broke up a year and a half a go so About 6 years total now because we’ve been talking since We broke up and fighting omg anyways I finally blocked him today because I can’t deal with his shit anymore. But yeah I barley ever went out while we were together definitely not with friends and once in a blue moon with him lol and it has made me so antisocial and shy when I never used to be like this.. mind you I have had daily weed habit For the past 3 years. I have one friend who I’ve had since we were 11 years old, we’ve been through so much together, one time we have gone almost three years without talking but we always seem to reconnect, she is like a sister to me. She has 2 toddlers now, who I love with my whole heart. I’m so proud of the mom she is but I can’t help and miss the old days sometimes and being able to just go out whenever and wherever or go party or clubbing without having to be back early idk what I mean is not having to worry about anything but yourself lol I don’t have kids yet and I still would like to do that Idk but I’m so anti social and Almost closed off to other friendships even though I do want that. What should I do? I find it so hard making new friends LOL just had to get it off my chest.. I have no one to vent to :(
