What is the most likely penalty I will receive for the crime I committed?

I have been accused of a Class A misdemeanor in the state of Texas (assault- family violence) due to attacking my mother while undiagnosed with bipolar disorder. After being bonded out of jail, my mother urged me to be admitted into a psychiatric hospital for treatment, during which I was diagnosed with my mental illness.

She stated that she wanted to drop the charges and hired an attorney in my defense, yet I am concerned over which penalty I’d be facing should the state still choose to pursue the charges, regardless of my mother’s wishes. My lawyer claims that it is highly unlikely that I will serve any jail time (although there is always the possibility).

Even so, I am uncertain as to what the court will decide in December once the prosecutor has spoken to my mother. Considering that this is my first offense and I have no previous criminal history, am I eligible for deferred adjudication or probation if the state still decides to pursue the charges?

I have been in recovery for bipolar disorder for the past few months and have not since reacted violently toward any individual again. Also, what are my chances of having the case dropped?
