Hi Noa,
Welcome to the group. I'd encourage you to read
http://www.lymenet.org/BurrGuide200810.pdf carefully. There may be coinfections in addition to Lyme that need to be treated.
Feeling worse before feeling better is pretty normal. Check out the thread at the top of the forum here for those new to Lyme - it contains detox methods that can help reduce the severity of the die-off (herxing) symptoms.
Because you got on treatment right away, you have an excellent chance of recovering.
There are some additional supplements and things that can be done to help your body fight the infections as well. Some of these are in the file link above, and the new to Lyme thread here.
I hope this helps...take care,
