Okay guys help needed.

Last week, I entered an emotionally stressful period of life. Lots of baggage from the past creeping into my present. My living circumstances changed somewhat, so I had to give up many of the routines that bring me security and support my well-being. I've also been sleeping poorly (I suffer from insomnia) which does not really help me keep the puzzle that is my life together.

Exercise has always been my lifeline. I started regular gymming in December so I am pretty much a beginner but it has drastically improved my well-being and taught me to love myself for the first time ever. Exercise has really helped with stress and anxiety.

However, last week, everything changed in a snap of a finger. I did not have the strenght and energy to do... anything. I could not push myself to do any exercises properly. For example, when doing seated row, I had to drop the weights in half. I decided to take things easier, which I have. Yet this week, my whole body has been in pain. My joints hurt, my lower back hurts, my neck hurts... And this just sucks because if this trend goes on I cannot even continue with the low-effort work-out that has kept me sane during these horrible days.

Why am I suddenly turning into a vegetable in constant pain? What should I do to prevent this? I am afraid I will lose the only thing I really enjoy - gym - but I don't want to fuck up my health either. Is my stress and my condition related or am I imagining things?
