How do I let my parents know I want to talk to someone again with out them thinking that something's wrong or that they did something to hurt me?

my parents weren't trilled about me seeing some in the first place and once my problems got "resolved" we stopped the sessions. My brother sees someone because he has ADHD and I honestly think I would benefit to go and talk to someone once a week or every other week. Before I went to see the social worker the first time my aunt and uncle thought it would do me good and I told my mom and she wasn't for it "last time I checked your uncle wasn't a therapist" (she uses that for everything I had an infection on my ankle and showed my dad "last time I checked your dad wasn't a doctor, last time I checked you didn't have cancer" My dads friend also looked at it)

The social worker was recommended by my schools guidance counselor who I went to see after my friend told them I was cutting. My mom never talked to me about it. If I didn't mentioned it to her she wouldn't have set up with an appointment. I had to push her to let me see one.

I don't want to ask and have them think that I'm cutting "again" (it's a once in a while thing. The counselor and my parents was stupid enough to believe that I stopped when they found out and when there were no more marks on my wrist) or that they did something to hurt me in someway. If I'm being completely honest I feel crazy. Like something is maybe not right mentally or something but I can't honestly tell that to my parents.

So what can I do
