What should i do for 3rd degree retail fraud.

Im 19 years old and i was recently taken in for retail fraud of the 3rd degree in michigan. im absolutely terrified as i read up on it and i was wondering if i shouls try to get a lawyer or something. i admitted to it to the police and have a hearing soon. i want to ask for an appointed lawyer but if its based of family income rather than my own i dont think i can get one. im terrified, ill pay any fines i just dont want to have this on my record or receive jail time as i am in college. if possible i also dont want my mother finding out as i think she deserves better than this and id feel awful if i put her through the stress of dealing with this as she deals with enough from me. I was thinking i could plea guilty off the bat and get a reduced sentence as i've never done something like this before and never would again.
