I feel I am in the same situation but it may just be a carry over from the initial SAD in winter.
For example - In my case - I worked hard this time last year to get on track to start college by taking relative medication and also playing that Nintendo DS game. Y'know, the Brain Training one?
This was all the while not knowing I had SAD and not knowing that I probably would need to use a light box as the winter crept upon us.
Needless to say I went on a downward spiral and left college after around 3 months. (I wont get into the details)
But the carry over from that has lasted around six months and could account for still "suffering" from SAD in even these summer months.
Can you relate to this at all? Has anything happened or still lingering in your life that you find hard to deal with that could be dragging you down?
On a more technical note - From a personal point of view - My first thoughts would be that it wouldn't be possible for SAD to be triggered in the summer.
Although on thinking about it a little deeper, if you are in a state where a week of overcast weather would upset you, to the point of saying you suffer from symptoms of SAD and that your life in suffering, then you are truly sensitive to the changes in weather. So this could be a type of SAD although on a short time scale.
I would say I am like this. This is why I would highly recommend using the light box even in the summer.
Although, I'm not using right now! I'm always here and there and can't be bothered carrying it around with me. But when I did use the light box a while ago it felt great and I will be using it nearer winter, for sure.
I don't necessarily suffer from Summer SAD but when the weather takes a turn for the worse and its grey I can definitely start getting SAD symptoms. For instance today it is grey and my office is quite dark and i feel rubbish!!
I feel rubbish when the sun isn't shining, even in the summer and well, where the heck is summer I'd like to know - I'm feeling really short changed......!
Good to know I am not "going crazy" having SAD in the summer, but it has been a shit summer here in Scotland. I have my light on now and feel so much better :)
