Shelvey put in an excellent display in midfield for the draw at Brighton.
He told Chronicle Live: "My head has not been turned. I have always remained focused.
"Don't get me wrong I have been very, very down because you want to play football. You can take all the money away because at the end of the day all you want to do is play football.
"There's nothing worse than a footballer training all week and then not playing at the end of it. It hurts you.
"You see the lads smiling and running around and you don't feel part of it. You have to stick by it and stick with the team and eventually your time will come."
Shelvey's career has been written off by some observers and West Ham have been continuously linked with a summer move.
But Shelvey hit back and said: "People can talk all they want. I am not one to listen to what people say.
"People say I have had rows with Rafa and things like that. It couldn't be further from the truth."
