The longer you are not working the harder it will be. Work will distract you. Can you do a phased return?
Have to spoken to your GP. I know antidepressants arent for everyone. They enabled me to cope.
I know how devastated you are feeling. You need to grieve. It is good you have counselling in place. Be kind to yourself.
It's time to take control of the situation. My ex had me dangling on a string telling me his mental health was all over the place and he didn't know what he was doing. All the time seeing someone else. But keeping me as his emotional and financial support.
Once I was certain ow was on the scene I drew a line. Told him to stop coming and going from the house. I went through the whole house and gathered up his belongings and put them in the airing cupboard. I moved things around at home. Got new bedding and some flowers. Small changes helped.
I talked to family and friends. They were so understanding. It helped just to be able to off load even though there were no answers
I claimed benefits. Single person deduction on council tax. Stopped paying his bills for his car and phone etc. Reduced my out going as much as I could. And put firm boundaries in place.
3 areas of contact:
The kids. See them eow and one night in the week. This didn't last long he was too busy.
House seek legal advice and this is to be managed through solicitor
Child support through CMS. Do not deviate from this.
I told him clearly there is nothing else I want to discuss with him. And grey rocked everything else.
Don't respond to emails or messages straight away. I give everything 24 hours unless it was about pick up times for the kids. Write emails and leave them before you send them. Take all emotions out of everything. Keep a journal of how you are feeling pour everything into that. Do not communicate with him about anything further.
He isn't the person you loved. He has betrayed you. Time to dust yourself off and start living your best life for you and the kids. You will recover from this I know it isn't what you want but many have walked this path before you and come out the other side.
