I have family history of ms, loss my sense of smell 10 years ago, migraines my whole life, getting worse during sleep, extremely forgetful, recently memory problems, depression and difficulty reading and writing (overall focus) could this be related ?

Neurologist: I recommend consulting a neurologist for evaluation and testing. Loss of smell years ago may have been a marker for future brain pathology. Loss of cognitive functions and depression are concerning. Your symptoms aren't characteristic of MS. Get the appropriate help you need by starting with a visit to a neurologist.

MS and other symptom: As suggested, please see your neurologist. After that you can consult a clinical psychologist. Depression, lack of focus, etc. are often secondary to dealing w/long-standing medical issues. Peace and good health.
