I'm a girl and I have a crush on a girl so what can I do?

if you think you have a crush on a girl, admit it to her/ask her out. she might like you back but might be waiting for you to let her know. make you sure both of you are alone. she may be shy if there are people around. just be calm and be yourself. tell her gently how you feel and ask her out. i wish you the best of luck...dont be nervous...
