From other posts, it's clear that you have been diagnosed, but not had much, if any advice or treatment yet. So, could be that you're now beginning to notice what your body is doing more, beiong aware of symptoms you've previously ignored. In addition, feelings of tiredness and can't be bothered can be symptoms of feeling down / depression, which accompanies a dignosis for many people, although feelings often improve as blood sugar levels are brought under control by a combination of changes in diet, increase in physical activity levels, reduction of body weight, and perhaps medication.
So, at this stage, take notes at any appointments you're offered with GP, diabetes specialist nurses (DSN), dietician, exercise on prescription etc. You may be offered an education course - different areas offer different patterns eg once a week for several weeks / whole day etc, sometimes only if you ask what's available, sometimes very soon after diagnosis, sometimes only after several months, different courses for people with type 2 diabetes treated by diet & exercise alone / with oral medication (tablets) / with injectable medication / with insulin etc. In general, most people on these boards would say take any opportunities that are offered - even if you don't learn much / don't agree with what you're told, you will probably enjoy meeting other local people wit htype 2 diabetes.
It's good to read up, but steer clear of scare stories and crank cures. Diet, particularly carbohydrate content, is controversial, to put it mildy.
Skin problems often begin to clear up as blood sugar comes under control, too. Heart problems need a range of actions - lifestyle changes that you can make, also prescribed medication can play a part for many people.
So, take a list of things that are worrying you / questions you'd like to ask etc to ask to your next appointment.
