Sadly seems that you are both low in Endorphins etc (feel good hormones that our bodies produce). Affirmations may help. Some time enjoying your own hobby / hobbies, shared hobbies, getting outdoors for a walk etc may be of benefit to you. We are living our life, possibly carrying out Responsible tasks, when these are for others it is nice, Respectful etc to express Gratitude. Seems that there is a culture of Self Preservation, Self Centredness etc nowadays. Especially in comparison to previous Decades etc.
I believe that Relationships, Interactions, Team work etc should be Discussed from babyhood through Nursery, school, University, Work places etc. As Respect, Self Esteem, Reciprocation etc are Valuable. Kindness and Consideration are Morals which would be reinforced in the past. Now it seems "Self" and "Competition" are to the forefront :- Sad, as we are Sociable Beings and it is "nice to be nice" and it is Good for the Health of Individuals and Society.
Best Wishes to you both. Be Kind to yourselves. Find the valuable relationships and encourage them to grow.Pets sometimes can help, as they are so loyal. If a friend has a dog, maybe you could spend some time in their company. Dogs can be great at being friendlyetc.
Keep us up to date on how you are. Best Wishes.
