really bad year

so i just need some support from some of you guys. i’m 15. on december 27th, i lost an old friend. i hadn’t talked to him in about 3 years and we fought all the time but he was always around. since then , i found out my boyfriend’s mom has a tumor and cancer, my step dads grandma passed, my aunt has cancer and a tumor, and my boyfriend and i are having issues. my sister is also in korea in the air force. i’ve also had a lot of anxiety about my ex. i’m not in touch with him, he just tried to reach out to me and my boyfriend. i also have a little bit of anxiety about my step brother. he untied my bathing suit top about a year ago. he doesn’t live with me, it’s just when i see him it makes me feel weird. any advice/ support??
