Roadblock landed me in jail and I lost my job, now what?

I was driving around with a friend of mine from work because we had weekends off and we was just chillin and cruisin  Well in April 17,2015 their was a road block and i had a sticker on my my back window that said “Legalize today Get high tonight 420” well i guess the cops thought we were high or something. I was very excited that Georgia is starting to get somewhere with marijuana especially the oil for kids. The cop asked me if i had any illegal drugs and I had remembered my jacket in my trunk had barely a gram of marijuana in my pocket. So I told the cop that I had the marijuana,a pipe and a grinder. I had left it in my car because I do not smoke around my child.  I only smoke when she’s in bed. Well I guess he thought I was high or something. He asked me to go to his car where he did the finger test and made me walk the line(after I told him the reason I probably looked high was because I barely got any sleep cause my daughter wasn’t feeling well for 2 days). Well I passed the dui test but went to jail and sat in the back of the cop car for a hour in handcuffs asking him to let me get out of the car to get fresh air because I was starting to panic cause I was upset with myself that I had forgotten about my jacket and I didn’t want to lose my daughter. Well he obviously didn’t care that my anxiety kept going up. One thing I can say, he only charged me with the marijuana. But the downside of it all I lost my job at Fieldale for getting arrested and I called and told them on Monday April 20, 2015 that I had gotten arrested and I wanted to be home with my daughter. I worked a full day on that Tuesday and then that Wednesday I worked a half day before they said I needed to take a drug test. I refused because I thought that it was messed up that I just got out of jail and they knew I would have THC in my system. Now I am trying to get THC out of my system to be able to get another job because I am a single parent and now my daughter has no insurance and I am afraid she might be autistic. Something has to be done with the marijuana laws for us that don’t abuse it and actually function very well on it. When I smoke I only smoke a bowl sometimes 2 and it helps with my depression and puts me in a better mood to where I actually want to spend time with my family because of all the things my daughter and I have been through for 2 yrs with her mother being on pills,alcohol and cocaine. I just hope that GA will get random people and watch them and how they act on marijuana to show that it is very helpful to some of us that use it for good and don’t abuse it.
