Amoxicillin and bladder infection

I am very reluctant to take any medications, but needed something for a sinus infection that wouldn't go away after 2 weeks. Received 10 day dosage. Drug worked to clear it up, but experienced a noticeable oncoming of depression and emotional detachment from life. This drug may not be tracked for psychological side effects, which might explain the lack of forewarning by doctor's et al, but it was a clear cause and effect in my case.

I'm a 29-year-old male, and currently taking Amoxicillin for a bladder infection. This is the 4th day taking it (500mg / twice daily). So far, the side effects I've noticed are insomnia, nightmares (when I do fall asleep), gas, and have recently developed this very weak, achey sensation in the front of my shoulders. You when you've been walking or standing so long that your legs ache the next day and they feel worn out? That's the type of weak, achey feeling I can compare the sensation to. And it gets worse when if lay on my sides, so it becomes even more difficult to fall asleep on top of the insomnia. Good news is my bladder infection has seemed to vanish after only the second day of taking Amoxicillin, so I'm thankful for that, as the bladder infection was very painful and discomforting worse than these nagging side effects from Amoxicillin.

Horrible experience with amoxicillin, which was prescribed for a nasty sinus infection. Major nausea, fatigue, feeling lightheaded and dehydrated. All I wanted to do was to sleep. Missed 2 weeks from work. The nausea was completely debilitating. But curiously, get hungry at the same time was feeling nauseated. When I do get some food, I have to force myself to eat it. Also had major headaches. Got sort of paranoid that something else was seriously wrong with me!
Have been off amoxicillin for a little over a week. Feeling VERY depressed and hopeless. I want so bad to get back to my normal life, but it is like I have no energy or desire to push on. I have to literally FORCE myself out of bed and to work. Very concerned here and do not want to have to start taking an antidepressant. Does anyone know how long these effects will last or what I can do? Doctor gave me an additional prescription for Cipro, but I am afraid to take it because I feel like I am trapped in a vicious cycle and these feelings will only get worse. I am not used to taking meds!!
