Oh, anxiety

Hey, im 16 years old. And lately i don't know how i feel anymore. So i have a loving boyfriend who is the best and i really love him and he loves him and i feel safe with him and loved. Im very happy with him. But than when im alone i feel anxious and sad. So one of the reason is my mom: Since 2018 she has been acting weird and strange. She gets upset for stupid things and she is very sensitive( so am i). She is irritable all the time and is angry for stupid things which piss me off. Also she has problems with my dad. And since 2018 is just getting worse. Like im so used of this bc it's hard to tell and it doesn't seem like a big deal, but it is. So 5 months ago when i got a boyfriend and she met him, things got a little better, i mean when he is here she acts diffrent because he loves him. But than is all the same again. And i know why is she like that. She has childhood trauma from her parents. And yeah I understand that is hard for her i guess but SHE IS MAKING THE SAME TO ME. And please don't say talk to her : because i don't feel comfortable with her and I talking. Okey but that's not the main problem like i lost myself. I dont know why and how but i did. When im with my boyfriend i cry almost every time because i feel safe with him and i trust him and than i tell him what is bothering me( because i can't trust my friends anymore). But im uses of this. He probbably think that im the girl who is always crying and everythinf and i don't wanna be like that. I wanna change. And also do you maybe now why do i get upset if he talks to other girls of if he just mentions them? And i get upset if he goes on a party. Probbaly because i have trust issues from the past relationship. But like i trust him 100000%. So yeah it's weird.
