That is really frightening. I know it is so hard. Are you waiting for housing and living with your partner's family? You have the puppy/1 year old?
It must be devastating to have left your home. I don't know what went on there to cause you to have to leave but it must have been major.
Stress has a huge impact on the brain, on everything. I forgot my purse when i went to the shop yesterday and could not pay at the till. I had to leave my shopping and on the walk home i kept saying 'i want to die' to myself. Such a small thing and you have had such a big change.
When you have a home, you will be ok. Can you hang on until then? You are a person, here, in the world, the impact your death would be is enormous.
Rest, eat, walk, look around at Spring. Think of the warm summer, the flowers, then the Autumn, pumpkins, fireworks, poppy day, remembering those very young men who had to go to war and died to keep us safe. Then Christmas. New Year.
They are times when we look after ourselves, eat nice foods, walk in the snow, pretty lights, they help us get through.
Your dog will help you. We will help you get through the days.
I do think though at this point you need to call 111 to get some professional help. Their job is to help you through this time.
Are you taking your medication? The doctor could arrange something for you to take for a while to help you feel less distressed and sleep well.
Basics, eat, wash, sleep and puppy.
Slowly, carefully, sort housing? current problems.
