Am i overreacting? Need some assurance:(

So i was diagnosed in july of this year and i feel like ive been managing my diabetes pretty well. But some days like today ive been high all day. Not super high but like 140-170 range. I get these occasional spikes that are stubborn and difficult to get back down and steady again without dropping to low but is that normal? Do you guys get spikes every now and then and even whole bad days where youre high or low all day? Or is it just me:( i worry about my health im only 20 and i feel like im pretty healthy in every other catagory.
