Levaquin and antidepressants

Im only 16 years old and ive been on levaquin for about 3 days now. My doctor told me off the bat that the only thing wrong with the drug were some "theories" on cartilidge damage, how ever, now i see for myself, and for many other people that is not the only side effect. He told me that no one under 18 is supposed to have it but i caught a severe case of sinutitus, and a uti which ive had for 2 months and nothing was working, so he put me on levaquin, once a day for 7 days. Ive now been having the following symptoms and im extremely scared!!
1. Constant fatigue
2. Extreme Migraines
3. Nausea, vomiting
4. Rapid heart beat (and chest pain)
5. Stiffness in joints and horrible pain...
6. Constant anxiousness, to where i cant get to sleep
7. Dizziness

Is there anyone i can talk to who's had these same problems? please email me or something im scared and i don't know what to do my mother doesn't believe me and she says its just a head cold....

Please help me!!
