I honestly think that Janelle is bi-polar or something along the lines of that. The way that she freaks out...It goes from 0-100, then flipped to 50. I don't think that she's addicted to weed. She's addicted to the way she feels when she's high. Which that usually means that she's trying to numb out (escape) or she's missing something (filling the void.) That's how alcoholics are, weed is no different. Especially if you have an addictive personality.
Leah obviously has daddy issues/men issues. Didn't she hook up with Corey on a one night stand after she broke up with that Robbie guy? (Her 16 & Pregnang episode.) Then to go from Corey, straight to another man, pregnant and engaged within a year of divorcing your first husband?
Chelsea is so spoiled, it bugs me to death. That's the only down thing about her. Her whole deal with Adam doesn't bug me as much as it does other people on this forum, mostly because I was that girl who couldn't get over her on/off bf.
This show needs more girls like Kailyn on. She's the only one (from Teen Mom and Teen Mom 2) who seems to have her head on straight.
