I have realized through my relationships with people that jealously is a natural thing that can happen to anyone .. Sometimes it can or cannot be controlled .. If you understand why you have those feelings in the first place it may be easier to find a way to control it .. These feelings may come from fear .. fear of losing a significant other because you don't realize your own self worth and you may feel they will find someone better .. fear that your friends will leave you out .. there are a lot of different fears I could mention that deal with jealously .. These fears could really affect you emotionally and sometimes even physically .. But if you realize why you feel the way you do it could help you cope with it .. you just have to find a way that works for you .. And remember that being jealous is okay to feel once in a while .. it is normal .. don't be ashamed if you feel jealous .. it is okay! Sometimes it can come to a point where you start putting the blame on someone because of how you feel .. in some situations it may be the other person's fault but other times that might not be the case.. You need to realize if it is the case or not .. Just remember that feeling jealous is a natural thing for every human being .. You just need to find a way to not let it get out of control .. Know your self worth .. understand why you feel jealous .. and find a way that works for you to control it ..
