I’m sorry your going through this, your children are lucky to have you.
You are awesome and I’m in the thick of it at the moment. I reach out to other parents at parks that my kids play with and ask if they want to
exchange numbers to let them know when we are next at the park and build from there.
Since last summer I’ve managed to get one friend for my son aged 8 and two sisters for my daughter aged 5.
Make time for yourself even if 5mins here and there, you have to have your cup filled to pour from it.
Stay strong
