Custody battle

going though a custody battle with my ex he has been place at my ex's mum and dads house as a place of safety,but that's rubbish because I have had no convictions harmed my son or anything there using my past against me,he sees me 2x per week for 1 hour each day,supervised and there is nothing wrong with me at all I suffer from anxiety and depression but they shouldn't be holding thus against me and there saying they are safety concerns how I interact with him and how I encourage him to touch things that are a danger,this is not trust he social work are taking children away from there mothers each year and it needs to come to a stop! People like me that have nothing wrong
