Returned Home From Holidays After 1 Week I Found Myself

returned home from holidays after 1 week I found myself feeling wiped, every opportunity slept through the day aswell as night, no energy to do anything around the house, and at the end of the week almost collapsed in work from feeling light headed, felt like my blood ran cold, wend to doctor and I had a kidney infection, since my anti biopics finished I've had itching in the vagina but doesn't feel like thrush, for quite a while now I've suffered from stinging after sex, could it be linked is there something else going on, Aldo I have prolapse bladder and bowel,
