Indecisiveness

I've been redoing my bathroom for the last two years... not in the "completely gutted, start from scratch" kind of way.  I can't seem to find a color scheme I like.  First, when I bought the house, it was all gray. Gray tile board on the walls, and that was it. The bathroom is tiny, and the only one in the house so it's not like I have an option of what I want to look at... I put up a basketweave pattern light brown wallpaper, dark brown trim, and a delightful multicolor striped shower curtain.  One of the cats felt it necessary to scratch some of the paper off the bottom part of the wall, so it had to go.  About a month ago I pulled everything down, planning on a colorful purple and gray room.  Wallpaper on the top half, a nice plum on the bottom half.  The plum was way to dark, plus being that I was painting tileboard, I decided I would create faux grout lines, with a white paint pen... This looked awful.  So, I painted over the purple with an olive green. This looks pretty good with the gray wallpaper... Yesterday while perusing the scrapbooking paper in Hobby Lobby, I had what I thought was a great idea- the one wall that was all tile board, I would collage! I purchased a mass amount of paper in purple, green, and a large flower purple, green, and off white pattern.  Today I took the purple, cut it into 4 inch strips, and created a border around the top.  Not bad.  I then continued the collage process on the one wall with all tile board.... eh.  I the green in the paper doesn't match the green I painted, which I realized that, the olive might be too dark, a lighter shade of green would be great. The collage doesn't look terrible, but I just don't want to look at it.  I don't know what I want, but I'm tired of that damn room being incomplete. 
My style.. I would describe it as... ecclectic.. I want my personal style reflected in my house, not overbearingly, but in a classy way.. I want to enjoy the room, I spend a lot of time in there.  I just can't decide. 

I guess decorating while in a less than desirable emotional state is a bad idea.
