I'm a single mum struggling financially, emotionally, etc etc and have been struggling with my son to the extent of conflict single morning ever single night.  Resulting on arguments and then upset. .... 

I spend most evening in tears because of the stress of everything...
Every single day he pushes and pushes me and after so long i react and then it all goes mental and there is tears. 

I just don't think I can cope for much longer 😢
There is an organisation called Early Help (not sure if these are all around the country) who do what it says on the label.  You can google them and self refer.  They will meet with you to discuss what is going on and work on ways to improve what is happening.  They will also work with your son to help work out why he is behaving this way and to re-educate him.    They really can help.
