First ever charge DWI Texas

I am a 19 year old (F).. and I got arrested for the first time ever almost a week ago in Tarrant County tx. I got in a car accident with another car not sure if the other is totaled, but mines is. Cops gave me a fst and arrested me on a dwi. I was not given a breathalyzer or a blood test.. Even when booked. I am in college and my major is criminal law.. I understand the contingent of this situation i haven’t ate since or been able to sleep comfortably since. if anyone has ever been in this type of situation what could my potential out come be ? I was told it seems the officers made some wrongs ( as in not drawing my blood or giving me a breathalyzer) and i could get the charges dismissed or dropped since it’s only a sft i was given, but i don’t have high hopes i feel like my life is over. I don’t have a lawyer as of yet and I can’t afford one i’m just in college Any advice or thoughts?? I can say I will never do something so stupid again this is real life and something so unfortunate to go through. I was told my only bond condition is to have a breathalyzer interlock installed but i don’t have a car at the moment. I have not received a court date and my name is still not popping up in the system when my name is searched by them.
