Thank you Michelle,
But similar suggestion was given by one of my closest friend; however the more I get these kind of the suggestions the more stronger bond I feel towards my sister. Also, I have a watch that was given by her this always makes me remember her. I tried to remove it from my hand but It's impossible. Once I had a thought to break down the watch on a stone but couldn't do rather I put my opposite side of the hand.
I have given her calls through my friends cell phone just to listen her voice. Literally don't understand as what's happening to me.
Almost all the people would say to forget her keeping self respect in mind, but my heart says otherwise. Also Please do not share any solution which talks about forgetting her or may hurt her in anyways.
