Want Linked Node to return self in getNext(0)

Question

I'm trying to make a getNext for my linked list that can return anywhere from several nodes ahead to itself.
How do I make a method that can return itself? I don't want to pass the calling object in with the parameters, that seems rather messy. I can't do previous.next or next.previous because sometimes those values will be empty.
Sample code follows, with highlighting for attempted legibility:
I included the whole class at once since I didn't want it to be spread about if more was asked for.
Session is an enormous user-defined class that stores a lot of data of widely varying types.
class NodeSession
private Session value;
private NodeSession next;
private NodeSession prev;
*{color:#0000ff}//constructors{color}*
{color:#008000}public NodeSession()
Session defaultSession = new Session();
value = defaultSession;
public NodeSession(Session q, NodeSession r)
value = q;
prev = r;
public NodeSession(Session q, NodeSession p, NodeSession r)
setValue(q);
setNext(r);
setPrev(p);
{color}*{color:#0000ff}//gets{color}*
{color:#999999}public Session getValue()
return value;
public NodeSession getNext()
return next;
public NodeSession getPrev()
return prev;
{color}*{color:#0000ff}//sets{color}*
{color:#999999}public void setValue(Session q{color}{color:#999999})
{color}{color:#999999}{
value = q;
{color}{color:#999999}}
public void setNext(NodeSession r{color}{color:#999999}*)*
{color}{color:#999999}*{*
next = r;
{color}{color:#999999}*}*
public void setPrev(NodeSession p{color}{color:#999999})
{color}{color:#999999}{
prev = p;
{color}{color:#999999}}{color}
{color:#0000ff}*//attempted jumps*{color}
public NodeSession getNext(int i)
NodeSession newNext = next.getPrev();
+{color:#0000ff}//newNext = current nodeSession, but only if next exists+
+{color}{color:#0000ff}//need some way to refer to the object I'm trying to manipulate so I can return it.+
+{color}+for(int j = 0; j < i; j++)
newNext = newNext.getNext();
return newNext;
{color:#0000ff}//more of the same
{color}{color:#999999}public NodeSession getPrev(int i)
NodeSession newPrev = prev.getNext();
for(int j = 0; j < i; j++)
newPrev = newPrev.getPrev();
return newPrev;
