I'd probably fail to go to the gym too should I lose music. Funny enough, my MP3 player recently fell ill. It didn't die completely, but it only plays out of one ear unless you squeeze the headphones to the right, the little screen is all a jumbled mess of pixels, sometimes it won't even load up and when it does, it takes about a thirty seconds to switch songs on occasion (and hitting play is hit and miss as to whether the song starts). Needless to say, it was time for a new one. It was like, a fifteen dollar MP3 player, though, so I should be happy it lasted me this long, being beaten up and all (I've dropped it so many times).

With cruddy music, though, I can't dance at the gym. Ever tried dancing at the gym in the racketball rooms, or where they do the zoomba lesson stuff? So much fun :D. Dancing for twenty minutes beats stars out of twenty minutes on the stair master, any day. Of course, you still have to do the stair master... and people start to stare at you if you dance on the stair master. It's not my fault if each stare falls down perfectly with the beat of the music! T_T

Also. Forgetting to eat?! Maybe you need tastier bamboo :D.

For self applied mood uppers, I'd also add:

Have a bit of chocolate (I'm talking even just a square from a Lindt bar or something of the like)
Get some natural light (even if only from keeping the blinds open for the day)

Those two are really important for me sometimes.

"Paint nails with that bumpy textured polish and then touch them"
Okay, this intrigues me. I'm a very tactile person, and it's one of the reasons why I love hands so much. I've always had this thing with texture, and I touch so many things. Neat things, cute things, gross things, and random things (like when I'm walking through a store, I'll just touch something when I pass by it, typically without thinking about it). Usually when I see something, my first reaction is that I want to touch it... especially things that most people wouldn't want to. Like wounds. There's this infamous picture on the internet of a hand that had gone through a paper shredder, and you have no idea how badly I want to touch it. The same is true for this equally infamous Photoshopped picture of fingers that are hollowed out and have a jagged, bony sort of look to them.

As a kid, I'd wrap a specific part of my baby blanket around my hand and rub it onto the side of my face. The blanket is a 3 x 3 grid with a heart in the center of each square made out of different fabrics that have different patterns on them. The middle one was this plain, less saturated green, and it was my absolute favorite. I literally wore a hole through that particular spot, and there are a few other hearts that are sorta worn and have thinner patches, but it's not nearly as prominent. I also used to take small pieces of Scotch tape and play with them on my fingers and palms, generally folding the tape over itself a bit (to make sort of a little cone shape) and then run my nails back and forth over it. I don't know how or why I started doing it, but it feels interesting and good--but only with good tape. There's certain types that suck, but iirc the green Scotch magic tape and the red Scotch magic tape are both bueno. It's been a few years since I've done it, but now I really want to.

Surprisingly enough, the textures that I hate more than anything and will not touch willingly are velvet, corduroy, suede, and pipe cleaners. You'd think that fuzzy shit would be my jam, but nope. I hate them. Hate hate hate those specific things, and they'll make my skin crawl--especially if it gets underneath my nails. Ugh.
