i bleached my hiar and it looks terrible

Hi, i let a friend of mine convince me to go blonde. Bad Idea. she bleached my hair and now it looks terrible. The top part is very yellow and the back is like light brown with an orangey color. The yellow is to bright for my skin color. We used a dark blonde over the bleached hair. I just want to fix this and cant afford to go to the salon. Should i try highlighting it or can i just color over it with a reddish brown color. Red looks good on me. Thank you in advance. I need help. _popupControl();
