Self-Injury Support Group
Whether you or someone you know or love struggles with self-injury, this is the community to discuss your experience, find support, meet others going through the same, and get advice on how to stop. Working together, we can help find alternative coping skills to reduce the urge to self-harm.

The thinking about cutting your food intake, it can cause belly pains and chest pains all on it's own, so that will not solve any of the aforementioned problems.
You could also do some stress relieve Deep Breathing and Relaxation Exercises to deal with the stress and anxiety your dealing with, those would actually relieve the symptoms and not cause new problems.
Take care,
Kat
