Mental health

Hi I am 14 years old and I struggle a lot with mental health, I have OCD where I will perform certain rituals to stop things from going wrong and anxiety and I diagnose myself with a life threatening illness ally of the time when I am suffering a headache e.t.c because that’s what I think it is . I have gotten better over the years and I am starting to deteriorate again so I was wondering if you guys could help me out and share some tips on anxiety, OCD etc

Thanks 💕
