I'm so sorry to hear that. I know how hard it is I dunno what I'll do when it happens to me. I'm still waiting and being positive. You can try again next time and also you can apply to other airlines for the meantime.
Don't give up try and try until u get it. My friend said she knows other ppl who tried out 9 times. Just persevere and I'm sure your hard work will paid off in the end.
