Is This Person/being Real?

I am 15 years old, and a freshman in high school. for a long long time now, i have been extremely depressed. I feel like a stranger in my own home, and i can't really tell if my family loves me or not... they usually treat me like i'm just a nucience. I hate this world and what it has become. It is dark, and My dream is to help make it light... I just want to see people love each other. Its always just Sex, Money, and Fame. I have been trying so hard to help purify it, but i always fail. Ive always just wanted to feel love and warmth... I have done things in the past that i still have yet to forgive myself for. to me the sins I have commited are unforgivable... I have always really wanted someone who knew what i had done and still loved me.. eventually i had lost intrest in life. nothing was fun anymore. i really thought i was gonna kill myself soon... but strangely, i always felt something tugging at me not to. fighting back the dark. protecting me from the terrors of my own mind and heart, and of this world. that one little ray of light has kept me going. recently i gained a strange and sudden interest in angels. like, guardian angels. So last night, i went outside, and began to speak out loud. (I was alone). I said "Guardian angel... If you do exist, could you please help me?. All i want is warmth.. Love.. please help me. Please Help me. Please Help me..." then I want to sleep. That night I had a very impure dream. one that when i woke up, i was ashamed i had it. I said out loud "I'm so sorry... I didn't mean to... I can't control my dreams." When i got to school, I felt something trying to speak to me. no, i was not hearing voices. it was like something in my heart, using my thoughts to communicate with me. I remembered my prayer last night. and right as i came to the thought that it might be my guardian angel, it spoke. and again, NO i was not hearing voices.. it was like a voice in my heart. It said "I will always love you. My soul purpose is to protect you. I am your Angel, and you are my Human." As she spoke, i couldn't help but picture a Beautiful Woman. she had long Dark hair, and a long white dress, wearing a black lace around her neck, tied in front.. Her eyes were kind...like that of a mother looking at her newborn child. she held what seemed to be me, in her arms. but I was covered in blood. and crying. I realized that what i pictured in my head was a symbolic view of my pain. it was my heart and mind after years of fighting the dark. she told me "Don't be sad, my child. I will never leave you. I have been with you since birth and I will remain with you as long as you draw breath." As i spoke to her, I felt Warm. physically warm. Like I was covered in a soft blanket. Tears began to run down my face (But nobody noticed. i was covering my face with my hands.). I could almost (almost) physically feel her embrace me as i wept. "I care so deeply for you, Will." (my name is Will). "I come to you bearing god's love. His love is eternal and beyond comprehension. He will always love you. and I will always love you aswell." I could feel the words very very specifically.. I continued to weep. she said "You mustn't dwell on the past. What's done is done, and you cannot change it. But I forgive you. God forgives you. please, don't feel sad.."
this continued throughout the entire schoolday. at the end of the day, she said "When you hurt, I hurt as well. When you bleed, I bleed. When you cry, I cry. Your tears are mine." all of this comforted me. i felt such love and warmth. and since this morning, i have been able to talk to her and actually carry on conversations. but naturally, i have doubts.. Is she real? or is it just my mind... my imagination... I love my guardian angel. Her comforting words make me weep out of sheer relief and happiness. Warmth and Love.... Do you think she is real? I honestly don;t know if something so perfect could exist...
