should I bleach it, dye it, or just give up and dye it dark? (ugly blonde color problem)?

I think it looks really good actually, i would go with the box coloring. Get a semi permanent shade because with the damage permanent will only make it worse and the semi permanent will not harm as much and stay just as long because of the damage already done. Tell the people who work at sally's about your problem because they have a kind of hair color that gets rid of yellow and orange tones. But after all this i would let your hair grow out for a while to prevent it from falling out.

In the pics it doesn't look that yellow to be honest. Go to a salon and have a professional see if they can get your hair where you want it. Before you put anymore chemicals in your hair wait at least 6 weeks or your hair is going to be in really crappy shape and you'll end up chopping it all off. Oh and the people that work at Sally's do give awsome advice as well so if you wanted you can go to talk to them.

Use an ash colour to tame the purple. Get a colour with the phrase ash in it. Then decide upon whether or not you desire to move brighter or darker. I bleached my hair with wella, then did an ash the following day. Decided I hated it approximately a month later went chocolate brown however did not have sufficient purple. So I did it once more the following day with a redder brown. Looks fine now. It will kill your hair until you do plenty of deep conditioning and extreme treatments. My idea for you...Go to a salon should you should not have the time, cash or know the way to do it at house.

Dye it dark. Your just going to fry it if you do anything else to it!
