What Causes Tiredness And Fatigue After Going To Gym?

i m boy 27 .i have been drinking for seven years, an alcoholic. (also its been sixmonths i didnt even touch alcohol,i quited it.) . On 2010 june. i went for a body massage to a parlour. there a naked women came and didnt do any massage. she did a hand job on my penis for a min. & she kept a plastic cover over my penis and did a blowjob..as i was little drunk on that day, semen didnt came out...after that we both hugged and she didnt let me kiss her. and she kissed me only on my cheeks only 2 times..and didnt let me touch her bottom or cunt whatever shit u call it. and i went away..after 3 months i went to gym first time in my life regularlly and i started to get fatigue for 3 weeks..i felt very tired normally..but while doing workouts i didnt get tired. i was doing workout for 2 hrs daily..and reduced 5kg in 2 months.i went to doctor and he said must be vitamin defficiency/weakness because i didnt eat properly for a year & prescibed multivitamin tabs..my fatigue or tiredness went away in few days and lower leg burning or confusing pain was there for a month ...and went away.still continuing the mv tabs. But here its heavily cold after long time and got some small heat boils like things in my face..which i never had in my life..i m so confused whether i got infected?? ..(i didnt have any fever or cold or any other symptoms.).thats the only first time i had massage with a women in my life..and still regretting .....i m so confused..what should i do ?
