Forgetfulness and trouble focusing like this usually comes from stress, poor sleep, or anxiety rather than anything serious, especially when it has built up gradually. Low
vitamin B12 or an underactive
thyroid can also slow your thinking down, and both are easy to check for and treat.
Next Steps
A basic blood panel checking
B12,
thyroid levels, and blood
sugar is worth getting done. Also look honestly at your sleep quality and stress levels, since both affect memory and decision-making directly.
Health Tips
See a physician sooner if this comes with headaches, mood changes, or gets noticeably worse over a few weeks.
