I am so sorry for your loss, that grief must have been overwhelming for you. But just know that is normal. It is normal to feel lost after losing someone who has been by your side for 25 years. It is not easy to move on from that. However, time is the greatest healer. Allow yourself to feel what you need to. It might be worth seeing your doctor and getting a mental health care plan so you can learn some strategies to work through this grief. As quirkywords said, reaching out to others who are experiencing grief can also be helpful.
I hope things improve,
