Is it normal to feel the feelings of my siblings?

So my brother and my sister both left to go to camp at 6:45am there planes left at the same time but one was going to Minisota and the other is going to North Carolina! My sister got where she was going at 12:50pm and my brother got to Georga for a mid flight and he had to switch plaines! My brother said that his plaine was canceld in Georga that made me scared!! He acually had a 35 minute delay! So they got on the plaine and they were in the air for about 15 min! Then there plaine made an emergency landing and now im freacked out!!! Should i be feeling this way or should i just let it go? My brother is curently in georga by himself and he's only 14 years old.
