My life needs some fixing!?

OK my friends shelby,chrissi,marrissa,and Jessi all hate Lindsey. I got really mad at Lindsey, so then my friends were all happy, then Lindsey called me and said I'm sorry and all that. The thing is my friends will not get along with Lindsey at school and it causes huge drama. Then i have a boyfriend. I'm bi but he dosen't know it. He is against bi or anything so should i tell him? But its still a secret that im still bi. I also have a girlfriend. Anjel my girlfriend i love sooooooooo much. Nobody knows about htis relationship though. She is so great to me but she ends up not caring at all about our relationship. Also there is all the name brand cloths and having your hair just right like my friends. Im so jealous of them and now they want me to do all that stuff but i just can't afford it. So please help me!!!!!!!Please give me some advice!!!
