Need some support if anyone can relate

Im 42 years old and since then my body started changing. Started feeling ill and tired, sleep disturbances, open my eyes several times a day, head pressure, sore scalp, 2 episodes of vertigo, feeling lightheaded sometimes during the day, in other words, my life took a turn. I feel down and worried. Sleep used to be my refuge and now is not. Went to my doctor, my blood work came back perfect according to my doctor. I checked it myself and everything is in range. Maybe perimenopause , i have no idea. Last year my ferritin level was 5 but it went up to 17, still low i think. Don’t know if that has anything to do. Not anemic, my hemoglobin is 14.5. Anyone can relate?
