I want to help him by means of a spell lifting the dark cloud surrounding him. but I'm not sure if this is the right thing to do. I really need some advice of what i should do. I have a strong feeling inside telling me I should do something but not sure of I should because I don't want to accidently hurt him.
I would have to agree, start by asking your friend if he would mind, or better yet, would like a bit of energetic interjetion. And IMO, a formal spell could be a bit of over kill. IME, continued positive energy can do alot for someone who's a bit down on themselves. I think that you really need to watch certain things when dealing with magic, and basing a self-esteem issue on a spell isn't exactly the way I would go.
