Hello and welcome. Have you discussed this change with your doctor? I suggest you do so soon.
Here is a copy of side effects and you appear to be experiencing some of those symptoms. Please read carefully. I think it best for you to see your doctor very soon under the severe category. Especially check the mood changes and see how that rates for you. Then write back and we can discuss further.
All medicines may cause side effects, but many people have no, or minor, side effects. Check with your doctor if any of these most COMMON side effects persist or become bothersome when using Wellbutrin:
Changes in appetite; constipation; dizziness; drowsiness; dry mouth; headache; increased sweating; nausea; nervousness; restlessness; taste changes; trouble sleeping; vomiting; weight changes.
