22 with gray hair 😩

I'm going to be 23 in a few months and have noticed I'm getting A LOT of gray hairs. I pull out as many as possible but I just can't get them all. My natural hair color is very, very dark and I haven't colored it in 2 years...so I'm thinking its time to even though I really don't wanna. But seriously gray hair at 22?!?! I feel like it's way too early!!! At this rate I'll have a full head of gray hair by the age of 30! Ugh
