Hi Charlie –
Have you tried exercising? Maybe a 30 minute walk or run maybe with a little uphill for a good workout ? It will help your racing thoughts and it might help you feel better about yourself. Also maybe trying to eat better. My husband was diagnosed with ADHD and we found out his blood type and we researched the best foods for him to eat. I think if you concentrate on yourself fill your time with positive things and changing your diet and stay on your meds you will feel better and your wife will like what she sees. You can’t depend on her coming back to you. You have to be ok without her. And if she comes back I hope you keep your promises you make to her and be her prince that she needs.
God Bless you!
