Keep working on yourself. It takes time. Better times are coming. Control anxiety and GAL GAL GAL
Enjoy time with D4 and feel the freedom not the loneliness. Try some meditation, IC, running, butterfly hunting, whatever. Learn to live with yourself first. Get into amoafwl.
And man...you are not alone...that’s a feeling and I’m sorry you are feeling like that but you have the power to change it.
