There is some weird feeling that trapped in my heart...

I don't really know why these days my heart got a feeling that like have a big stone on it...... I feel hard to breath.... Got two of my friend told me that maybe I have liked someone just I didn't notice it...... Do I really liked someone???? Is that you??? I don't really know...... I just know that finally I can put someone else down and I don't want to "pick up" anyone now...... I feel so confuse now..... This matter interrupt me while I working and sleeping...... I really start to hate it..... Do anyone can save me?????? Argh!!!!!! T.T
