・it's hard to say, but
・I hate to bring this up but

「說起來可能有點難以啟齒。」可以用英文 it's hard to say, but 或 I hate to bring this up but 來表達。

It's hard to say, but it looks like I couldn't shoot the moment you succeeded.
（說起來可能有點難以啟齒，但好像我沒能拍到成功那一刻的照片。）
※ shoot（拍照、拍攝等）

I hate to bring this up but our flight time is 11 o'clock, so we have to head to the airport soon.
（很難說，但我的航班時間是11點，所以我很快就要前往機場。）
