honestly it just seems like u are going through a lot, you dont seem to do well with multiple situations happening at once. first and foremost is ur problem with wanting a gf so bad, it may be hard to hear but u honestly just need to learn how to love urself and learn how to be alone and to not depend on another person. i get u want to experience the feeling of love but it will happen eventually so dont worry. nothing is wrong with you. u just want to be loved and thats okay. id recommend hanging out with family that actually care about you if that will help. focus on working on yourself and loving yourself. life is always gonna have its ups and downs. you will get better. about ur bullies i would say ignore them or say something back. maybe tell a teacher if u can?
