I am 48 yr old woman. On antidepressants and anti anxiety meds. Finding it extremely difficult to lose weight. Still get my period monthly.?

Medications. There are some medications that can cause weight changes as side effects. The hormonal changes can also contribute, the stress which can be part of depression anxiety symptoms. Best will be to review meds with your psychiatrist, have a hormonal assay checked and watching diet and exercise. I know it can be frustrating but can be done with effort and support. Good luck.
Check thyroid. It is extremely difficult for everyone to lose weight. Get your thyroid checked by the doctor.
