PLEASE help: im in danger zone!

[adinath]

I really APOLOGIZE PLEASE for such long post... Please help me im having different disease which i feel very ashamed to tell...and i some times feel like dead i donot know how to get rid of such thoughts i always get some sexual feelings(actualy i use to see such lust films but not often still... i tried to change my thoughts but in every real life situations the lust feeling will add and i diverted my mind many times but only for temporary purpose) for every small things in life i will get such thoughts and its very hard to get rid of such thoughts I worked for one MNC co. and in order to get the permanent solution i resigned recently & im a GREAT performer if do not get such thoughts. I know i can do "THE BEST" work if i dont have such feeling but i really need any mantra to get rid of such thought and feeling. WHENEVER I get such thoughts i feel more pain in the center of the eyebrows(kundalini) and also i feel like somebody is resting on my hipps. IM sure that it is not a physical thing i feel like some DEMON has come in me and making me more pain and one thing every one will turn negative to me EVEN parents in such situation, even if i dont think y will I get? I KNOW THIS thinking is foolish but believe me its ALL happening without my notice and I FEAR a lot for every thing. I daily chant hanuman chalisa, ganesha mantra,saraswati mantra, vishnu mantra(4 lines), laxmi mantra...but still god is not listening to me.. In simple words it acts as a layer of such feeling is stopping me to do achieve success or doing any thing. I want to study further and achieve big things in life but this thing is acting as a boundary to me and not making me to do anything. IS it related to some dosh? or its thinking(im sure that it is definetly not due to me! because i really see many people in life who watch such films(believe me i use to watch such films but not often) but still they are normal why me? is it a shaap for me?) HELP me with a reply
