I know where you are coming from I suffer with mental health issues and it effects my life in many ways even school work gets to me I have considered speaking to a teacher but they tell parents it happened to my friend but luckily she wanted her parents to know she still speaks to the teacher when her anxiety starts but I don’t want my parents to and I don’t want my teachers to know as I don’t trust them, so I speak to a counsellor on childline it’s free you can either email them, call them or 1-1 chat. It helps me because they understand you better as it’s there job as they have helped many other people also they don’t tell anyone unless they think your in serious danger and they don’t judge. I have been suffering with mental health issues for 3 years and none of my family knows but i think it is getting worst that’s why I want to consider seeing a therapist but don’t how to do that without anyone knowing but my counsellor did say I can see my GP alone and tell them how I feel. So they childline offer good advice my opinion
