Here's what I think your tune is in standard abc. I've assumed your notes convert to abc as:

     sionnach   abc
     A          A,
     C          C
     D          D
     ..         ..
     G          G
     a          A
  

(The only note that seems odd in the transciption is your g at the end of your 2nd line, which I think should be G (but maybe not!)).

Here's the abc version based on that:

X: 1
T:Pressed Man's Lamentation
M:2/4
L:1/8
S:sionnach's transcription from Hooks And Nets
K:Dm
A,2| D3 D| E3 D|(CD) D2-|D2

w:Our_ friends we must bid a-dieu,_
FG|A4|GE F2-|F2 E2|(DE) (D^C)|A,4-|A,2
w:For the press gang_ they_ have press_ed_ us,_
A,G,|A,3 F|E2 (FE)|D4-|D2|]
