Well - it's a lesson learnt hopefully, Danielle. Read the instructions - they're there for a reason! It will show you the amount to use per square metre or yard, so take time to look at that if you use any products in future
As KT says - even feed alone if over applied would do the same.
If you have bare areas in your lawn normally, you need to address the reason(s) for that. It's usually shade, dampness, compacted ground - or a combination of all of them. Aeration, by spiking those areas with a fork, and re seeding with a suitable grass seed later should help, but you'll need to wait until the effects of the application have disappeared.
