Well ocd sucks

Yes, yes it does.
First there isint a time that i see my grandma that i dont have this intrusive toghts about how i could have alzimer and then i have to pray a gazillion times before i feel okay.
Then when i´m praying the intrusive toghts with swaring (i dont realy know how to speel it ) comes to me.
Then theres the," oh you know God talks to you."
"Realy how?"
"like troght the bible , prayer , your mind"
SAY WHAT MY MIND? And now i will have all this toghts that show that God wants me to do this.
So yeah but sometimes they are so ....repetetive like posting a video about a song in the group that i have on facebook and trust me people dont realy like it.
But i get afraid what if it realy is a way of God talking to me and then ... im rejecting it ? there where times when some stuff was about to happen that i got that wierd toght and then it was like ,"you know i dont realy like to say this but i´ve warned ya havent i ? "

Grrr I dont know what to do.
Religious stuff and OCD its never good.

Edit: I did it I posted it .... and the thing is that i feel the same ... i have the need for something ... just dont know what.
