you dont accept any person as guru unless you are firm. Put 100 % faith in maa and surrender her and pray her to put you out of this suffering. Chandi path will surely put you out of this sufferings as it is ment for that only and to fullfill her bhaktas Right desires. I suggest you two remidies, 1- you do japa of navarna mantra on any japamala and wear it before going to sleep. 2- you chant gayatri 1000nam daily
and apply this vibhuti. If anybody is trying black majic on you, certailly the above remedies will help you, but you have to do it continuously
for three months except 4 days of ladies natural problems.
