Need to vent

Im on a trip to new york for work and its my first time here. My cousin couldnt come because she already took a couple vacations too soon and my man is very unsupportive of this and refused to come. (The work is modeling nothing raunchy just regular commercial modeling). I sometimes get nauseous from my anxiety and On the way here i threw up on the bus i tried so hard to not but it just happened and i got it all over my mask, my pants my face my hair and some in a bag. My mom just stared and watched and i asked her for a napkin so i could wipe it off my face and she got mad because her carry on was organized and said i was messing it all up. She kept yelling at me and even now that we are at the hotel (which is very nice, i made sure to get us two beds so we’d both be comfortable and have space) she was screaming at me and some snacks broke open in her luggage so she got mad and dumped them all over the floor and on my bed i dont know what to do i just need some positive words my boyfriend isnt talking to me and im stuck here with my mom (i just turned 20 i dont know where i would go since we just got here) she just went to go smoke but i am so stressed out now this is exactly what i asked her not to do i feel so bad right now because ive upset my boyfriend, and now im stuck here with my mom going crazy i really didnt mean to throw up i just felt sick for an hr or two before i even mentioned it and tried to contain it in the bag i only wanted a tissue and now the past two hours ive been getting yelled at and stuff thrown places and i would talk to my boyfriend but hes mad because he doesnt want me modeling even though he raps and so i just feel alone and like I already want to leave and we just got to the hotel.
