I insulted Lithuania in my draft, now I am being sent to the army, I am terrified, what to do?

As the headline says, I went to the draft, I said I don't want to go, but they forced me to go, and I got angry and insulted Lithuania, now I'm going to get court and probably the army. Because of these stupid assholes I will have to give up on my university. I'm 20 years old and still live with my parents. I have no idea what to do. I am not the best person to be around, I get angry very quickly, I'm not very social, I don't know how I will get along with the other soldiers. I am very scared and sad, I really don't want to go, but I feel like I have no choice. My mum is also very scared, she even said that she is afraid to be left alone with dad, because he gets angry really quickly and is very aggressive when drunk. I am the only child, so I don't have any brothers or sisters. I am really scared, I don't know what to do.
