Amber Portwood has been doing a lot of soul searching since being placed behind bars on December 19.

In a letter to her brother obtained by TMZ, the 21-year-old Teen Mom star said she misses spending time with her family, including her 3-year-old daughter, Leah (with ex-boyfriend Gary Shirley).

"I don't think I'll ever take this sh-t for granted," a discouraged Portwood wrote. "I'm really scared I'm going to prison. I don't know what I'll do. All I think about is Leah and how she needs a role model. If I can get out, I can really show her what a good mother is."

"I don't want people thinking I'm this crazy bitch," the MTV star added. "I am a good person and I pray that I can change my life!"

Portwood — who also apologized for her poor penmanship, explaining that "the pens they give us bend so we can't stab anyone" — argued that she's not really an "endangerment to society."

"This sh-t is getting out of hand," she complained. "I wouldn't hurt anyone!"
