pulmonary embolism/blood clots

I recently found out a had blood clots in my lungs after a quick trip to the hospital for what I thought was a pulled muscle in my side. they think it was from the c section i had at the end of July. has anyone else had this and did they put you on blood thinners? I'm on xarelto for 6 months and i can't shake this awful anxiety that im going to drop dead from a blood clot or something.
