<human>: What is wrong with me? I have been experiencing: Severe fatigue, some nausea, headaches, slight dizziness, temperature changes. Over the last 3 days. I don t know what is wrong with me. I have been very stressed. I have been paranoid of contracting a possible STD, its been 5 days since I have had sex. Also I think I could be lacking vitamins or something needed. What do you think may be causing me to feel this may? I really appreciate any help. Thank you.

You have mentioned that you had sex 5 days back with the above symptoms. If you had sex with unknown person STD is a possibility.  Don't get panic, be calm and pay a visit to your local doctor and get yourself examined and tested for Urinary tract infection and STD for the relief of your anxiety.  Good luck
