If they ended the friendship over one smartass remark or argument then they didn't value your friendship. My group of friends from high school pressured me into trying ecstasy and after we all did it for a couple months, they quit. I told them I enjoyed it and was still going to do it. They told me that they didn't want me around if I wasn't going to quit with them land dumped me as a friend. I took it really hard and started doing X all the time. Lost my friends, developed a drug addiction and then lost my job because of caving in and trying X with them. Had no friends or job so I cleaned up and wound up joining the Marines. After boot I came back for a couple weeks and saw them at Dominos. Somehow they heard that I joined the Marines. They asked me if I wanted to hang out with them because I wasn't doing X and we could be friends again. I told them how I felt about the whole situation and to not say hi or anything to me again if they saw me around. Sorry for the long story but nobody needs shitty friends in their life. That person didn't respect you or love you as a friend and they don't deserve to be around you, not the other way around like they tried to make you feel. It takes time to heal wounds. Changing myself and becoming stronger as an individual helped me. Look online for different hobbie groups and things like that in your area with similar interests. It won't take as long as you think to fill the void they left. Sorry again for this book.
