Does using acid to burn yourself count as self-harm?

Yes totally. It's just another way or method to hurt yourself. It harms your body - just like cutting.

Yes. Anything that you do, including burning, cutting, scratching, biting, pinching, or other, that you do to hurt yourself is considered self-harm. Please speak to a listener if you are considering harming yourself!

The short answer here is yes. Anything that you do or use to injure or mutilate your body is self-harm. Strong acids would, without a doubt, damage your body tissue, so if you intend to use it for such purpose then yes. Since you are asking this question, I'm assuming you self-harm. This is a very serious issue and I would recommend talking to someone you trust about it or seek professional help. I could only imagine what trauma or issues you are going through that is causing you to self-harm. Always remember that you are not alone and their are people and resources out there that would help you.

In clinical psychology, an act is considered self-harm if (a) the person deliberately inflicts tissue damage to his/her own body, and (b) the action is used as a coping mechanism to regulate either negative intrapersonal (anger, dysphoria, feelings of numbness or dissociation, etc.) or interpersonal experiences (seeking attention or comfort, or trying to keep others at a distance). Under this definition, many acts can be considered self-harm, not simply cutting or scratching until blood is drawn, but also scratches that simply leave a mark, pinching, hitting, burning, etc. It's not as much about what you do but why you do it, that will define whether the behaviour is self-harm (referred to as "non-suicidal self-injury" in clinical and research settings).

If it's hurting you and you are doing it it's self harm no matter what it is so yes my dear burning yourself with acid is self harm

Yes, using acid to burn yourself does count as self-harm. Any act that is intended to cause harm or injury to yourself is considered self-harm.

Yes, doing anything to hurt yourself counts as self harm, cutting is not the only form of self harm.

Yes. I think any acts of hurting your body can be counted as self-harm. If any of you feel to do so, please consider seeing a therapist/trained mental help professional/other professional for help.

By it's very definition, yes. There are lots of different ways people self-harm, it's not just cutting, Anything that a person does to cause harm to their own body, or to inflict pain, is a self harming behaviour.
