Help me with the child support agency

Firstly Thank You For Giving Me The Opportunity .

Well here it is in short :

I Marty 43 male was with my partner Michelle fo 15 happy years we had two boys daniel and ashley 10 and 12 at the time

one day outta blue she dissaperers with the children I get phone calls threatening me not to try and find them had to call the police at one stage have crime number ect

I had a breakdown and tried to commit suicide i couldn’t even do that right

3 years later when im getting used to my own sad company her and new boyfriend decide they would like the house i paid for and live in

so i struggled to get a remortgage and gave her a cash lump sum of 20 thousand pounds that pushed my wages to the limit

during all this time i have not seen the children i don’t know where they are

no contact for a further year then i get a letter from the csa saying they were unable to contact me
so there going to take 91 pounds a week direct from my wages I called them and they tell me its the law this is compleatly crippling me. i dont eat for days iv missed 1 mortgage payment and the future looks bad on my spredsheet my bills now exceed my income and i live a very poor lifestyle. Iv always worked and have a solid cv . This System is unfair Im Struggling Starving and Suicidel

Thanks For Listenin
Marty
