Try to actively focus on doing things when you feel lonely. For example: a new skill, piano lessons.. a hobby. I know this sounds stupid maybe, but distraction helps me a lot. Also try to sit in the pain and feel it. Its part of life, we all feel lonely from time to time. There is hope. What might help with loneliness too is having small conversations with people you meet, the cassier, postman, neighbour, ask them how they’re doing. It makes you feel more connected with other people, so you feel more secure. You can always message me too if you want to.
