Can someone suggest some tunes?

My ex-best friend is getting married. We've known each other for twenty-two years now. We were inseparable for twelve. We grew up together like sisters. Then our families moved away. But we both moved back in high school & once again we were like sisters. We've been there for each other through high school drama, suicidal times, countless failed relationships, alcoholism, chain-smoking, anorexia, family drama so intense it warrants police intervention, southern baptists chastising our lives, pregnancy scares, moves away to college/to live with bfs/back in with parents, etc...etc...etc... It just got so hard. We both changed so very much. We check in about twice a year. See how things are. We still love each other, but too much has happened. We'll never be the people we once were & the people we are now wouldn't be friends. The past is past. No regrets. Anyway, she called last night to tell me she's engaged. We've been planning our weddings since we were little girls. We were to be each other's maid's of honor. But that was a long time ago. She's asked me to be a bridesmaid & I've accepted. It may not be like we always dreamed it, but I'll be damned if, for her sake, it's not close. Anyway, I'm kinda coping, dealing, etc... I feel very honored that she's asked me to be a part of it. I'm really happy for her. I'm just sad that it won't be the way we dreamed it. I'm sad that everything's changing. Plus, several of my girlfriends have gotten engaged lately & I gotta admit, it leaves me feeling pretty lonely. Need some tunes to help me sort things out. Just need to make a great mix cd to drive around & smoke to. Something to clear my head. Songs about old friends, change, loneliness, no regrets, lying, moving on, etc... Please help. Anything ya got, just throw it at me! Thanks bunches :)
