Skin Sensitivity :(

What i wanna say is... I kinda REGRET to donate my blood :(

my skin become sensitive after blood donation (it was in March). 

my skin gets reddish and swell very badly after getting mosquito bites, and the worst part is, F**KING ITCHY!!! it needs weeks to heal and left scars although i dont scratch them at all. 

 scary ritez? it's, very ugly and disgusting. i got them mostly on hands and legs which easily get mosquito bites and some on the other parts of the body.

i've bought a lot of cream for the bites from pharmacies, apply them everyday after bath.

so what i did next was prevent myself from getting mosquito bites. i wore long sleeves shirts or cardigan as well as long pants and brought mosquito repellents with me all the time, apply them once i settle down at anywhere regardless the place has mosquito or not. the mosquito repellent has unfavorable smell where most of my frens dont like it, but screw them, i dun1 my skin to get worst and cover up with scars, arrghhhh! sorry frens :(

now my skin actually get better without new bites, just scarsssss, hope that they will disappear as time passes.

it has been months i didnt apply lotion as the weather is too hot. skin gets sweaty and very sticky if applied lotion on it. and yesterday, i applied lotion on my skin before i get to bed, ended up, skin irritation! it gets reddish and itchy. mayb the lotion spoiled coz i dun use it for about 3 months? is tat possible? or my skin juz too sensitive after blood donation? i threw the lotion into rubbish bin tis morning thou. 

what is wrong with my skin???!! SAD! T______________________________T

if it goes worst, im going 2 see doctor dy... :/
