Im so stressed and i have no one

I have been really stressed for weeks. I tried to ignore it with some tv shows and uni work but i lost it last night. I suddenly lost myself, but no, i didnt do such a thing. I just felt lost. I cried for hours. I needed a hug just to calm me down or someone to talk with. My moms room is next to mine. I needed her hug i wanted to hug her and cry just to calm me down but then i remembered everytime i cry she always say, "you'll be ok, you dont need a hug bcs you will cry more, just pray to God". I did. It calm me down but i just needed a hug. But everytime my brother sad or cry, my mom always hug him even though hes older than me. Im not jealous. I was raised this way. But im only human, i need someone to calm me down everytime i lost myself. A friend? I had one. To be honest i have a lot. But i only trusted this one. She was my bestfriend, i can be myself around her, i can cry without afraid being judged but she out of nowhere ignored me, i dont know what i did. She never answered. I cared about her, shes like a sister for me. We used to talk about everything. But she suddenly left. I dont know. I have no one. I have trust issues since my parents told me that im weak, i cry for nothing but it wasnt nothing, it broke me
