Will I get jail time for criminal mischief 4th degree and two counts of harassment?

I am 19 years old from New York and I have court coming up. I was arrested for criminal mischief 4th and 2 harassment 2 chargers. I lost my temper in a local store and ending up cursing out 2 employees who filed a police report which is why I’m charged with the 2 harassments. As I was leaving, they yelled out the door at me I was already mad at the time I picked up a cardboard sign that was on the sidewalk and threw it at the window and it cracked which is why I have criminal mischief 4th degree. I have no prior arrests on my record. I do not want to go to jail. What is the worst that can happen? Will they let me pay a fine and do community service or probation and offer to take anger management to stay out of jail. Is there a way I can get the criminal mischief down to a violation if I pay the fine and community service or probation? Thanks for reading really hope it all works out in the end. I am young so I’m still learning I do not want to mess up again.
