Anyone here with teens?

My son is a senior and he’s always battled with anxiety at school but this year in particular he has been missing a lot of school. He has missed 9 days 3 of them being excused. And 26 lates. He is late at least 1 day a week if not 2.. and by late I mean he doesn’t get there until 10 which is when his bus comes to bring him to his technical school. So he misses 3 classes in the morning and leaves for his other school and then comes back for one class. I just bought him a car for Christmas and give him gas money when he needs it. I have already taken his PlayStation away from him and this has been the longest he hasn’t had it it. I told him once he has gotten to school on time for a full week I will give it back. He wants it’s back so bad but just not enough to make it to school. Then I gave him $20 last week and said this is that last I’m giving you. If you don’t have money for gas after this then you will need to get a job or find a ride. He doesn’t like that but it still doesn’t stop him from going in late. I have stressed way to much about this and am finally trying to let it go and not get the best of me. I don’t know what else to do.. does anyone have any suggestions? My son is on the honor roll. he says that being late once or twice a week isn’t a big deal because he’s still making honor roll. I’m afraid he will eventually get lowered grades and might even have to go to summer school. I’m afraid collegess will look into his tardis and not want him in their school.
