Emotional healing (to me) means to resolve a reaction, feeling and behaviour towards an issue either subconsciously and/or consciously. So if you have a phobia towards mice, emotional healing could involve healing the incident in your past that has lead to it, the unconscious processes going inside your brain that resulted in your fear of mice and so on. There are many different ways to heal emotionally, which is why there’s a lot of emotional healing titles here.
Basically if you don’t know why you have that phobia, it doesn’t matter as the healing titles here will either clear them out by their own subconsciously and/or you will be consciously be made aware of why this occurs so you can resolve them consciously.
Thinking of it like taking medication is not bad but the way I think about it is that it’s closer to having muscular imbalance and pain due to bad posture. Eventually, you need to stretch out your body to relieve tension, stress and pain in that area of the body. Then your posture will be back to normal. That’s what (most) healing titles are for. Building muscle to achieve a better physique is like running a status/social/romantic title.
