I want a normal ADC once in my life!

Hello guys,I'm writing this because I need normal adc once in my life,everytime I go to solo Q I pick supp as my primary role and Top as second..I have lost 3 in a row because I get stupid ADC scared to attack,my mmr has fallend down because of 3 loses in a row..So I started game today and went support,whole my team is B3,B4,and I got Miss as my ADC.She is so stupid blaming me(Blitz main lvl7) that I don't know how to play,everytime I go into fight and ping for assist she doesn't come she stays at turret but she is saying to me whole time let's attack..I would really but really like to have nice ADC so we can play rankeds almost everyday..I'am S4 currently with 3 loss in a row at 0LP,so please any silver good ADC to add me at LoL(EUNE) and message me... I'm 17y old..
