Search Results: sick of her mouth

so recently my mother's friend came to our house with her kids and i didn't know she did because i was asleep. so they came and knocked on my door and woke me up like 5 times but i was very sick and i actually have bronchitis. so her 10 yr old daughter was upset and crying that i didn't play with her the rest of the night. so the next day her mother came to pick up my mother and they went out, my mom came back and told me she had a problem with me. my mom told me that she thinks im rude and that im a bad kid, wtf? so i ask my mother what i did wrong, and she kept on giving me different answers and wouldn't tell me straight. so my mother tells me to call her friend to talk to her and apologize, and i asked my mother why i should do that. i called her and asked her what her problem was ( nicely), and she said it was because i didn't acknowledge her daughter. I'm 15 and her nasty ass daughter treats me like trash and she's 10, so i dont really think she deserves it anyway even if i was in shape. i have never bad mouthed my moms friend or even talked back and im very respectful.
recently she's been trying to get close to me and sometimes makes small remarks about me that dont even make sense because she barely knows me and she forces me to hang with her loud ass kids and her homosexual son (im not homophobic, she just wants me to be her daughter in law and to convert him secretely). When i first heard she had a problem with me i thought i was a joke because i have treated her with 100 percent respect! but even her son told me she is super insecure and acts strange all time and likes to argue with him, WHAT DO I DO TO AVOID HER? and was i wrong? because i didn't even know i made her daughter feel sad (i was sick and dizzy) or that i "purposely" chose not to acknowledge her. my mother says she is jealous of me because of my skin tone and my weight, which is hard to believe because she causes a lot of drama for that shit.

I don't want this to be too long, so I'll try to shorten it.

- I got sick on Wednesday: Freezing, headache, and sore throat. Thursday was the same, except I couldn't talk at all.
- Friday (or today): Woke up with a stuffy nose, I could talk a little, headache wasn't as bad, and coldness went away.
- Sometimes I feel faint when I stand or move. It feels like blood is rushing to my head.
- My ears keep ringing at random times throughout the day. They hurt as I type this.

It seemed things were going well, but I noticed this weird taste in my mouth. It began around noon I think, and hasn't gone away. It wasn't until I blew my nose (and saw red) that I realized I was tasting blood all day. I checked my gums and they're not bleeding.

What's wrong with me? To shorten it: I taste blood coming from my throat, I had a nose bleed, my ears ring and hurt, and I get lightheaded often. Is this a bad sign? Do I need to see a doctor?
