Bactrim DS and sleep

I cannot sleep, my body is tired but my mind is racing, Im paranoid and anxious. Light case if nausea, off and on headaches, just a little depressed not severe though.

I have had every side effect that the medicine states that you can have. I normally don't react to medication, but with this stuff, it is ridiculous! I took it for an infection that I had in my ear and from the very start, I felt loopy every time I took it. Then I began almost like hallucinating when it was bedtime. I was extremely tired, but could not get to sleep. Finally, the morning after I finished the prescription, which also happened to be my birthday, I broke out in hives from head to toe. I appreciate that my ear was healed, but now I have a whole set of different problems just from the meds!

I have taken one pill of bactrim ds, also known as sulfameth/Trimethoprim 800/160. I too about lunch today for a spider bite i got the night before my leap surgical procedure so during that the doctor said he thought i had gotten THAT COMMUNITY STAFF like MRSA that 99.9 percent people have but not my body is itching all over, i have chills, and my back is burning, I feel different all around kinda like im in another world and very sleepy but cant sleep. Im not really having many emotions or feelings either,I just feel like I don't care and that is taking 1 pill at noon and 1 around 10pm. I don't no what to do I have 2 babies under 2yrs of age and I need to get better but i don't no if the med is safe.
