The below fits me to a "T". Was so grateful to find this on the site. Thanks, MsVickie. Thought it deserved to be repeated.
Depressed mood
Feeling hopeless, sad, discouraged, or empty.
Loss of interest or pleasure
Inability to experience pleasure. Nothing seems to interest you anymore, including former hobbies, social activities, and sex.
Appetite or weight changes
Significant weight loss or weight gain—a change of more than 5% of body weight in a month.
Sleep changes
Insomnia
or oversleeping (also known as hypersomnia).
Psychomotor agitation or retardation
“Keyed up,” unable to sit still, anxious, restless
or sluggish, slow speech and body movements, lack of responsiveness.
Fatigue or loss of energy
Physically drained. Even small tasks are exhausting. Can't do things as quickly as you used to.
Self-loathing
Strong feelings of worthlessness or guilt. Harsh criticism of perceived faults and mistakes.
Concentration problems
Inability to focus. Difficulty making decisions. Can’t “think straight.”
Memory problems.
Irritability
Grouchy, easily annoyed, and frustrated by little things. Angry outbursts.
Aches and pains Depression can cause or exacerbate many
physical symptoms, including headaches, backaches, diarrhea or constipation, abdominal pain, and aching joints.
People suffering from
depression often show distorted thinking. Everything looks bleak to them, and they hold extremely negative views about themselves, their situation, and the future. Trapped in their pessimism, they obsess over their problems and blow them out of proportion.
These are signs and symptoms honey. I think you will find it a common thing with weight loss surgery.
