How can I add a footer in the first page without missing the page numbering for other pages?

Question

My objective is to add a footer only in the first page of my document, but the problem is that the page numbering is missing. How can i please fix this issue and have the footer only in the first page without missing the page numbering for all pages? Here is the code I'm using:

before \begin{document}:

\usepackage{lipsum}
\usepackage{fancyhdr}
\fancyhf{}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}
\fancyfoot[L]{my sentence}
\pagestyle{empty}

and after \maketitle:

\thispagestyle{fancy}

Here is the full code:

\documentclass[journal]{IEEEtran} 
\usepackage[cmex10]{amsmath} 
\usepackage[english]{babel} 
\usepackage{graphicx} 
\usepackage[utf8]{inputenc} 
\usepackage{lipsum} 
\usepackage{fancyhdr} %\fancyhf{} 
\renewcommand{\headrulewidth}{0pt} 
\renewcommand{\footrulewidth}{0pt} 
\fancyfoot[L]{..footer sentence..} 

\begin{document} 
  \title{..the tiltle..} 
  \maketitle 
  \thispagestyle{fancy} 
  \begin{abstract} ..the abstract.. \end {abstract} 

  ..\\ ..the body.. \newpage ... \newpage ... 

\end{document}

For something like this on a single page, I like to use tikzpagenodes. (Don't forget to run it twice.)

\documentclass[journal]{IEEEtran} 
\usepackage[cmex10]{amsmath} 
\usepackage[english]{babel} 
\usepackage{graphicx} 
\usepackage[utf8]{inputenc} 
\usepackage{lipsum} 

\usepackage{tikzpagenodes}

\begin{document} 
  \title{..the tiltle..}%
  \maketitle 
  \begin{tikzpicture}[remember picture,overlay]
    \node[anchor=base west] at (current page footer area.south west) {my sentence};
  \end{tikzpicture}
  \begin{abstract} ..the abstract.. \end {abstract} 

  ..\\ ..the body.. \newpage ... \newpage ... 

\end{document}
