A 17-year-old Britney Spears wrote this breakup letter to her first serious boyfrend, Reg Jones.

I mean, I tried to tell you the way I felt in New York, which was really bad timing with your dad coming up and all, but I know if I were you, I would want to know if you didn't love me anymore. I've been feeling this way for a long time now, but I was just scared of what would happen if you knew."

Right now I don't have time for a boyfriend. When I do see you we argue. You say everybody argues like Bryan and Blaise, well, I don't want that. I know it's really hard to have a girlfriend who travels, but it's even harder to have a boyfriend who doesn't have trust in his girlfriend. You literally pushed me away. I couldn't take it anymore! I'm not in love with you anymore, but I will always love you and care about you. I've had a great two years with you and will think about you daily. This is hard for me too, you know. I wish nothing but the best for you. Who knows, two years from now, or even ten, we may get back together if it's meant to be, but right now you need to let me go.

Tell your family I said hello & I miss them terribly.

Love,Britney." 2. In early 1961, Marilyn Monroe was dealing with depression, insomnia, and dependence on barbiturates, plus recovering from surgeries. This put her in an emotionally fragile state, so her friend and psychiatrist Dr. Marianne Kris suggested she check into the Payne Whitney Psychiatric Clinic in New York. Marilyn agreed, believing it would be a place to rest and recuperate, but was horrified to find herself in a far more extreme facility than she imagined. Seeking help, Marilyn wrote to her acting teacher Lee Strasberg and his wife Paula. Bettmann / Bettmann Archive Her letter said: "Dear Lee & Paula, Dr. Kris has had me put into New York Hospital - psychiatric division under the care of two idiot doctors - they both should not be my doctors.

You haven't heard from me because I'm locked up with all these poor nutty people. I'm sure to end up a nut if l stay in this nightmare - please help me Lee - this is the last place I should be. Maybe if you called Dr. Kris and assured her of my sensitivity, and that I must get back to class so I'll be better prepared for the 'rain.'" Bettmann / Bettmann Archive "Lee, I try to remember what you said once in class - "that art goes far beyond science."And the science memories around here I'd like to forget - like screaming women, etc.

Please help me - if Dr. Kris assures you I am all right - you can assure her I am not! I do not belong here!I love you both,MarilynP.S. Forgive the spelling - and there's nothing to write on here. I'm on the dangerous floor - it's like a cell. Can you imagine cement blocks? They put me here because they lied to me about calling my doctor and Joe and they had the bathroom door locked so I broke the glass and outside of that I haven't done anything that is uncooperative."Thankfully, Marilyn soon managed to get a message to her ex-husband, baseball hall of famer Joe DiMaggio, who flew to New York immediately, confronted the hospital administration, and demanded her release. With his intervention, Marilyn was transferred to a more compassionate care center in a less restrictive setting. She later credited DiMaggio with "saving her life." 3. Notorious gangster and crime boss Al Capone wrote this letter to his son while imprisoned at Alcatraz Federal Penitentiary sometime in the 1930s. Unique Nicole / Getty Images It reads: "Well, Son, here is your dear Dad, with a letter for you, and pray to God, it will find you in perfect health... Junior keep up the way you are doing, and don't let nothing get you down. When you get the blues, Sonny, put on one of the records with songs I wrote you about to Ma, to you, which I sure go to town playing them and about 500 more on my Mandola. I also have to transpose my music, from Piano Copy, as the Music people don't print Music for the Mandola, so I transpose one key to another." Bettmann / Bettmann Archive "Sonny, I got a Song like 'Rainbow on the River,' that was sung by Bobby Breen. Now what I mean by transposing is the Song 'Rainbow on the River' was in the Key of 3♭, I have to transpose it down to 1♭, and Son of mine when I come home, I will
