Jenelle Evans is back in rehab, again. It's been a rough few days.
The trouble Teen Mom 2 star checked into a detox center last month and was released Friday, only to check back into a rehab facility after a tough few days.
Her addiction to heroin is believed to be the root of the problem.
“Jenelle was in great spirits before she went in," says a source.
"She is really hoping that she can get control of her life. She is bi-polar and she’s had a really hard time balancing the medication she needs for that."
