Please help I am extremely upset and I have no idea what to do?

Right now I am hysterically crying. I need to talk to someone. I should have a while ago. But I can't open up to people afraid that they will judge me. I can't talk to any of my friends or parents or siblings, I tried talking to my mom but I just can't she doesn't help at ALL even though she thinks she can. I am so frustrated/angry/upset about everything about my life right now I just want it to stop I need to talk to someone how can I? I would love to go to a therapist but my mom somehow doesn't understand that I NEED TO GO TO ONE. She's so oblivious and annoying I can't take it. But anyways HOW CAN I TALK TO SOMEONE NOW?! Please help I need it I really do.
