Attention problems

Hello,

I’m an ambitious 20 year old and get pretty good grades in my degree which is writing focused. I’m capable at writing but everything takes me a long time because I get so distracted. Lectures in university are impossible because I’m forever being distracted. Recently I’ve been interning and finding it SO difficult because I just can’t remember or pay attention to things. It’s frustrating because I know I’m intelligent but I feel physically like its impossible. My mum suggested I go for an ADHD test? Any experience?

Love x
