How does Victor feel as he travels through England?

From the text:

If this journey had taken place during my days of study and happiness, it would have afforded me inexpressible pleasure. But a blight had come over my existence, and I only visited these people for the sake of the information they might give me on the subject in which my interest was so terribly profound. Company was irksome to me; when alone, I could fill my mind with the sights of heaven and earth; the voice of Henry soothed me, and I could thus cheat myself into a transitory peace. But busy, uninteresting, joyous faces brought back despair to my heart. I saw an insurmountable barrier placed between me and my fellow men; this barrier was sealed with the blood of William and Justine, and to reflect on the events connected with those names filled my soul with anguish.
