It seems like things are getting better for several cast members of "Teen Mom 2." 

Jenelle Evans, one of the most controversial stars of MTV's reality series, proudly announced on Twitter on Friday that she already received her diploma in medical assisting from Miller-Mote Technical College. 

The 23-yeaar-old recalled everything that she endured in the past on top of her school obligations, but she still managed to finish the technical college program. She also shared that if she can go through it all and still get the diploma, others can do it as well. 

Evans also thanked her mother Barbara for her constant motivation and for encouraging her to never give up on her goals whatever hurdles arise. The two had a long history of dispute because of some of the life choices that she made in the past. 

However, probably the most touching post that Evans tweeted that day was the simple celebration that she shared with her mom, her two sons, 5-year-old Jace and 1-year-old Kaiser, as well as Kaiser's father and her on-again, off-again fiancé Nathan Griffith.  

Evans and Griffith were involved in several nasty fights which sometimes ended up with either one of them in jail. Seeing them all together in one picture means that Evans' future will be brighter compared to her tumultuous past.

But aside from Evans, another "Teen Mom 2" star is currently in a better disposition. On Sunday, Leah Messer posted a new photo on Facebook of herself and her three daughters Ali, Aleeah, and Adalynn. This is the first photo taken after she was released from rehab. 

Messer had a rough time last year after her ex-husband Jeremy Calvert filed for divorce and accused her of cheating on him with the same man who she had an affair with before she married her first husband Corey Simms. She also had to go through a very painful custody battle with Simms, who believed that she is an unfit mother to their 5-year-old twins Ali and Aleeah. 

Now that she is out of rehab, she can finally take care of her girls to make up for lost time.

Both Evans and Messer are featured in "Teen Mom 2" season 6, which airs Thursdays on MTV.
