Are you on any Psych meds? If your "okay" in the morning but if the evenings are always your rough times .. Could it be the time of day that your meds are wearing off? Just a thought.

If medication(s) aren't a possibility then you need to look into changing your nightly routine, Could be anything from , exercise to what your eating for dinner to planning your evening to avoid having time to over think and worry.. It's often hard to determine how to make changes.

Do you have a T (therapist) ? Therapy can often find patterns and learn ways to cope and make changes that will improve your daily living.

Hope your feeling better
