I cutted out all high carbs, eat just whole food or occasionally some sugar like mussels with white wine, i cant give up this

but it doesnt contain much..then Ricola candies , i discovered it does contain sugars so i stopped to eat it, and i do sport regularly, as soon as i cuted cards, eat regularly and have breakfast with low carbs like pasta, fish,chicken, i feel ok , just had hypos at night but when i discovered its exercise that causing it i eat something before sleep, like few nutts ,apple or dried appricots.
i dont think i am forgeting now, and my brain works good probably, but i dont remember the things i learned last academic year , before holidays. we started work on stuff i learnt few month ago and these i forgot. not completely, just needed refresh memory.
that few months ago was awfull as i didnt know why i am tired, sooo moody,irritated,depresed, angry.everything and everybody goton my nerves., being sick, my grades suffered.i went trough hell and after hypos came in i knew its diabetes.
i dont know what people trough about me before, nobody had a clue why you are like you are. but i just worry if it affected my brain..yet i have to be ******* careful to avoid that hypo essp. at night (which i cant manage always) or i lose memory and have depresion for next two,three day. i can do a sligh mistake in forgeting to eat and it will affect me for long.
i am doing somethink creative in design and i might as well lose the enthusiasm i had before. i ate for reakfast oatmeal with banana and cinnamon as dr said i can eat it, i felt great but in half hour i was getting low again. so i really have to eat something heavier straight away in morning, i cant eat my fav oatmeal or mussli, it gives me hunger and hypo...i also have pain in left chest and cant catch a breath during swimming. i dont know why, during running i dont have it.
plus i want to have kids as i am over 30 but i cant, maybe in a two years but i think its a great risk anyway. they will not give me proper job because sometimes i just get stressed, then tired sleepy. plus forgeting things. i might end up on benefits, childless, with houndreds of desease and surgeries. :***:
