stress because of GDM

i'm super stressed. i'm tired physically and mentally. 33weeks now, with borderline GDM. nowadays i eat lesser and lesser, i dont eat junk food, i eliminate sugary drinks of all forms. Its a must for me to exercise before meals and after meals. for my blood sugar level be okay. when i get too tired and fall asleep after doing housechores, wakeup check my 2hour blood sugar level its high 😭 i'm feeling so stress i dont feel like eating anything at all. everything i consume is not good enough. i just wanna cry cause thrid trimester is already so very hard with the backaches, the sleepyness,tiredness,anxiousness. i dont even know what to do anymore 😢
