I got fired

I’m 20 F. I didn’t graduate a college with masters but I graduated with a medical administration certificate in associates. I did an online course at the institution of medical and business careers. I can’t find a job as a medical receptionist anywhere so I started looking elsewhere. About 5 weeks ago I got a job at a restaurant for 16.50 a hour. It wasn’t anything special but when I don’t work I get depressed and sad and I feel like a loser. I like having a job and something to do. The training has been going good until Tuesday. When I get anxious/nervous I sweat a lot on my face. I mean a LOT. Like I’m cracked out or on drugs. Tuesday was very busy and I guess I looked nervous and I started sweating loads on my face and my manager got concerned. I was making drinks. On Tuesday drinks are $2 for alcohol so lots of people ordered drinks non-stop. I was getting bombarded with loads of drink tickets stacking up and I got slammed. Of course every drink was made but it might’ve been slow according to them. I thought I did a good job despite sweating on my face a bit. My co workers are stuck up white girls, I am too but they are like the snotty kind. Private school girls. So I thought my shift was going good, they didn’t make it seem like I did a bad job, I left and everything was good. The next day I come back and the general manager is there giving me odd looks. The other manager says to me “can we have a chat”. Now I have no clue what this could be about because I assumed I did a good job. I am training by the way. This is my third shift on drinks, each shift is 2 hours long and it’s so busy so I figured I did a good job. My manager starts catching me off guard going, “so what happened Tuesday?..” I didn’t think anything happened I thought I did a good job. She starts telling me where do I think I went wrong. I DIDNT THINK I DID ANYTHING WRONG. She starts asking me a bunch of questions basically interrogating me about my shift that I allegedly did a terrible job. She said all the crew and managers were talking about it and she wishes she was there to “see”. I feel so upset. She continues to say “we are here for you! So what would it take to help this? How long?” So I didn’t think I did a bad job like I’m new. I’m training and it’s my third shift at drinks, I don’t know why they are expecting me to be a mixologist. She started making me feel bad and stuff and than asking me my whole shift “u OK?!” I felt very uncomfortable. Again, I made all the drinks perfect, on time, and I went home. Next shift, the manager texts me and says I “don’t have to come cause it’s slow. Next day ( today ) I receive a message from my manager saying “after speaking with everyone me, we decided not to continue with your employment due to performance concerns.” They than removed me from the whole schedule. I texted back asking if we could call and he didn’t respond. I sent a message to my other manager asking where I went wrong and no response. I than sent another message to my manager who told me I’m fired that it’s unprofessional to leave anyone on read as a manager and he said he’s dealing with a “personal matter” like what a clown! He than said he will call me tomorrow. I asked if he was ACTUALLY going to call me tomorrow since he lied the first time. Let’s see if I actually calls. I’ll update.
