Whether you are a light worker or not is something that you have to decide for yourself. My sense is that you do have a strong level of compassion about you which is a really positive thing. If you are compassionate and intuitively sensitive, the next question is what are you going to do with it.
If you want to get serious about it, i would suggest getting some formal training in the area such as what is offered through this website. I truly don’t believe some people randomly just become light workers, although i don’t claim to know everything on this subject.
The good healers i’ve met arrived there through training, hard work, patience, self-examination, persistence, and dedication.
