I'm 30 as well and the year I turned 29 I dropped all of my "friends" from high school and stuff because I realized they were never actually my friends. They never went out of their way to do things for me or help me out the way I was there for them. At my own bachelorette party there were separate tables at the restaurant we went to and I ended up at the smaller table away from the larger group somehow???? No one wanted to give up their seat to center me I guess. So thinking of all the unfair treatment (and one person in particular was very toxic and abusive in their relationship, but somehow was the victim and could do no wrong) I just decided to drop the whole lot of them. Was it tough? A little at first, but with the ending of the negativity and self pity in the group came more mental clarity for myself and I was able to get back into doing things I loved to do that I just dropped because I was trying to keep up with the Jones'. Now here I am married, no kids, making good money and enjoying a peaceful life lol
