You Told Me to Update and You Always Seem to Want to Know My Thoughts

This is for someone who means a lot to me. A thank you of sorts. I've never met you in person, and rarely hear your voice. There are many periods of time we don't even text because of me being to shy or even scared to talk to you, for fear of hurting you or making you hate me. And yet every time I muster up the courage, you're there for me. I've hurt you so much. I've betrayed you. Deceived you. And I never deserved you. But you loved me. And even when I broke you, you forgave me and remained my friend. You still find it in your heart to love me as a friend. You still never leave or hurt me. You've helped me so much. You pick me up when I fall and make me smile through the tears. You never stopped supporting me. When I felt worthless, depressed, full of rage, when I cut, when I wanted nothing more than to die, you were there. To stop me, to soothe me, to make me feel like I was worth something, loved, cared for, and listened to. We've never met in person. I rarely hear your voice. I end up avoiding even messaging you at all at times. I haven't even known you for very long. But here you are. So thank you. For everything. For saying hello when we first met. For talking with me. For being my friend. For staying with me. For putting up with me. For loving me. For helping me. For being there for me. For being you! For everything! Thank you! I don't deserve you and nothing I can say or write or scream can ever convey my gratitude and love for you. I love you. Thank you! And I'm sorry. I'm so so so intensely sorry for everything I've done to hurt you. And I'll do whatever I can to make sure I never do it again. I'll do my best to make you happy. And I'll do whatever I can to be as great of a friend as you are to me. So, I ask you selfishly, stay with me, for as long as we can remain together? Allow me to try to be worthy of you. I'm sorry. I love you. I don't deserve you. Thank you.
Honestly; I could never stop feeling this way about you. So once again, I love you.

P-p-please, don't l-l-leave me. . .
B-b-but, y-you p-p-p-probably sh-should. . .
