jealousy?

have anyone of you ever experienced this, when your older brother or sister has a gf or bf, and hence has little to no time to fit you into their now busy schedule of lovey dovey sweet sweet love? well i did. i remember the time when i was 13, i was kinda unhappy when my sister came back from india with another guy by her side. somehow, i had this rly annoying yet strange feeling felt on the heart, as if i'm about to lose something important to me, or something catastrophic is going to happen. i wasn't used to the changes that have taken place, given that my sister was , well u can say always thr for me to disturb and annoy, 24/7. i didn't rly liked her bf at 1st when i was younger. to me, he was the evil man that has come to take my sister away from me ( ahh kids mentality, what to do? xD) i've even talked bad about him at times, out of what you can simply call, jealousy ~ @.@ my sister literally changed a lot from what she used to be after she started indulging herself in the world of romance. nt her problem rly, just the narrow mindset of a jealous lil brother. but i guess its normal ~ anyway, things are fine now that i'm older. eventually, even our beloved brother and sister will have their own lives one day, their own family and their own story to tell. hahahaahha but ironically, i'm kinda facing this same old problem again. not to a really great extend, just a pretty mild one.or maybe our bond is not even worth 30 mins of yum cha time together :( oh well my sister wen mei should know what this is about LOL hahahha xD
