Anxious little boy

Hi , my son is 12  

He was bullied at 2 different schools which has crushed his confidence he now will not go to school to the park to the shops , no where really , he has no friends apart from  who he plays online with , I struggle to get out some days due to my own mental health and I have my other son who is 7 who is also autistic with greater needs, 

I feel  stuck and isolated and have no family support 

I feel I’m failing the boys as they are not enjoying what’s outside in the world and just feel really sad
