Excerpt: Because clothing can hide physical injuries, and inner turmoil can be covered up by a seemingly calm disposition, self-injury can be hard to detect. However, there are red flags you can look for (but remember — you don’t have to be sure that you know what’s going on in order to reach out to someone you’re worried about): Unexplained wounds or scars from cuts, bruises, or burns, usually on the wrists, arms, thighs, or chest. Blood stains on clothing, towels, or bedding; blood-soaked tissues. Sharp objects or cutting instruments in the person’s belongings. Frequent “accidents” – someone who self-harms may claim to be clumsy or have many mishaps, in order to explain away injuries. Covering up – a person who self-injures may insist on wearing long sleeves or long trousers, even in hot weather. Needing to be alone for long periods of time, especially in the bedroom or bathroom. Isolation and irritability.
