I'll start with some background on my issue:
Since around 17 I have had a history of pretty severe low moods. In these cases I've always just told myself I need to snap out of it. I tell myself content and happiness comes from my outlook on life, and this is something I (should) have complete control over. Anyway, I'm 22 now and I've been pretty bad at following my own advice. I spend way more time than what I would consider normal or healthy being sad and mopy. Particularly bad moods are often catalysed by self esteem issues I have, but not always. Sometimes (like at the moment) they are started by something really small that I know shouldn't bother me that much.
I'm not always sad however, I have some really great days, and I appreciate the fact that I am really lucky that I have a great family and plenty of amazing friends. Because of this I have never seriously considered that I might be depressed.
Skip to now. I've been feeling very down for the past 3 or 4 months. I'm not unfamiliar with low moods, and I usually feel better after a few months, however this is worse than usual and its gotten to a level where I feel like its time I get some help.
However I don't really want to go to a professional. It is something I would not be comfortable doing, and I also do not want to waste their time.
But if I did go, what is likely to happen? What is the procedure that the experts do after I tell them my concern? I'm from the UK so my first point of call would be my GP (NHS)(free public national health care).
I have read on the website that they often prescribe some minor life changes, such as exercise and diet. I feel like this is what will probably happen. Can anybody expand on this? What other minor life changes would they prescribe? If you know, please could you go into some detail? I currently have an okay diet, and I walk about 4 miles a day. This doesn't seem to be helping though. I could do with a more detailed prescription of these "minor life changes" that are supposed to help.
