My question involves criminal law for the state of: TX

Hi, I was arrested with my cousin 12 years ago at the age of 16 for shoplifting & was bailed out, I got fines, community service & probation. I got arrested again 12 years later for helping a friend in Dec 2012 at the age of 28, I got fines, community service & 1 year probation. During my probation time, I was caught at walmart for shoplifting merchandise under $50 recently in June 2013, the police came & look me up in the system. He gave me a citation, telling me to go to court on this date (*) & let me go. Please if anyone can tell me what will happen next? I'll go to court on the date said in my citation. But I was told if you are caught 3 times shoplifting, that's a felony & will go to jail for 6 months to 2 years. Please tell me if I need to tell my probation office what happen & I wonder why it didn't show in the system that it was my 2nd times before this recent one. Please if anyone can tell me if I need to get a lawyer & will a lawyer be able to help me? Out of the 3 times, 2 wasn't my fault, even though all was stupid choices but please if anyone could tell me what will happen next & what I need to do? Please let me know if you, yourself have been in the same situation or knpw someone that is.

Thank you very much, really appreciated any helpful information. God bless!
