awww..Kaika..that stinks!!
I hope it feels better..aloe vera, asprin, noxema or a cold shower helps with the stinging.
I'm so increadibly pale I burn really easy and I forget sunscreen all the time..I got burned in D.C. and I have a slight sunburn from work.
What I started doing was if I knew I was going out in the sun I put the sunscreen in my bag and that way when I opened it I would rember.
Or I just set a reminder on my cellphone.
I hope you feel better!!
