pls who ever u may be,my advice is that u get some one with higher faith since ur faith is low to assist u in prayer.but remember to stay away from evil becos nature can not be changed.if you are the type that steps on people's toes be cautioned.the person threatened to killed u for a reason u never revealed?
note:from this moment change ur belief immediately,that what you are passing through is not from any one.
have the believe and faith that u will be well,say it to ur self after every 10 minutes.
learn to pray that god shd heal u.
feel within u that there is a change for better,think positive about the person u are suspecting.
finally don't try what ur friend has adviced because it do u more harm if the person is higher positive forces.(i know what i mean here).
if you need further assistance hit me up.
