Knowing someone does it is a sickening feeling. I feel so worried for them all the time but I also understand it's something you need to do. It was sometimes the only way I could cope so I get that. Although I'm a worrying sort of person. So just don't get offended if I worry a lot.
I guess, I'm really clingy, jealous and over-protective.. I annoy myself haha. But being there for them is good, you can constantly talk to them and know what they're doing
