Being loved by you

After Olivia and I hugged a doctor walked in. He looked really busy.
"How are you feeling?" The doctor asked looking at me straight in the eye.
"I'm feeling all right. What happened, why am I here?" I asked curiously.
"I think you should ask your sister..." The doctor said and walked out of the room quickly.
"Liv.. why am I here?" I asked my sister who needed a shower desperately.
"My... boyfriend caused you to faint.. and stuff.. I don't know but I was scared Amy.." Olivia said slowly.
"Why would you care? You always let him abuse me with his words.. you are rude to me too, so why do you look like you've been hit by a bus? Why are you even here?" I asked annoyed.
"It's because I.." Liv started.
"Because what Liv?" I asked.
"Because you're my damn sister and I LOVE YOU. I know I don't act like it and I drive you insane but I do love you. I just-"
"Save it Olivia. I don't believe you." I said unbelieving what she was saying.
"Let me prove it, we can go to the park or go to starbucks together. Please just give me a chance."Liv said determined.
"Fine.. but first tell me what he did to you. I know Joesph did something, I can tell. Did he force you to-" She stopped me from finishing my sentence.
"No.. he didn't.. look I don't want to talk about this.." She said looking at the tiles on the floor.
"I'm sorry but I just had to ask.. Olivia I know your annoying but you're still my lil sis. I care." I said honestly.
"Lets not talk about this." She got off the bed and looked out the small window in the hospital room.
"Okay.." I said worried.
"You will be discharged today. The doctor said you'll be fine.. and just remember to drink lots of water." She told me still looking out the window.
"Okay thanks for telling me Liv." I thanked her.
"No problem... oh yeah, I meant to tell you something." Liv said awkwardly.
"What?" I asked as she pulled my cell phone out of her pocket.
"When you got to the hospital I took your phone and I noticed a text from an unknown number.." She said looking at the tiles again.
"What does it say..?" I asked beginning to feel afraid.
"Look for yourself." Liv said handing me my phone.
Who is this from?
"Who do you think it's from?" Olivia asked looking up from the tiles.
"I don't know.." I lied.
