Yes and no. As organisms in environment emotions could be defined as our bodies reaction to our environment so yes if your environment changes then of course your emotions will change. So there's that. However if you're asking what I think you're asking which is for some sort of explanation for the observed changes in your behaviour that have been caused by changes in your environment, then I could try to sound all knowledgeable about this and say "Sure! Seasonal Affective Disorder (SAD) is a well known syndrome etc etc." However SAD is not an explanation for your condition, it's merely us categorising phenomena and then saying that what we observe is an explanation for what happened, when it's really not, and in fact this act by its very definition is an observation of what happened and not an explanation.
So to sum up, have you observed changes in your physiology as a result of changes in your environment? Of course, and that's normal. It's almost a statement of the obvious when you think about it. Do we have an explanation for this in terms of psychology? No, not if we're being intellectually honest about it. Personally I'd argue that it's not a psychological problem at all, but a natural bodily reaction to a change in its environment. It just so happens that we as a society have begun to medicalise normal bodily reactions to environmental changes, claimed that because we have them that there is something wrong with us (as opposed to something being wrong with our environment) and started giving them names such as SAD, or anxiety, or depression etc etc.
