It sounds like your body was attempting to fight off a virus but when our bodies systems aren't functioning on full battery,we aren't as resiliant as we should be to resist illness. Look at our body in terms of an electric circuit board, if there is a break in the circuit, then there is a break in the communication to complete a task.
Can I suggest you take a look at Bioenergy Healing. RaphaYadTM Bioenergy Healing has a scientific basis to energy healing that can access your bio-electromagnetic circuitry system to rewire your body and mind, by way of pressing some master reset buttons to move you beyond your current boundaries. It is a non-invasive hands-on/off treatment that can pinpoint the root cause of your underlying symptom or issue and release the blockage / memory pattern.
