For the past several weeks I haven't felt myself. Firstly some basic data about myself: I'm 5'10, 130-135lbs, 32 year old Caucasian male. I suffer from allergies and take Claritin, I am also allergic to penecillin. I take excedrin for migraines on occasion.

For symptoms, I have been feeling overall fatigue. Great difficulty wake up in the morning as I feel very groggy. This week or so I have headaches that fade in and out. The past few days I've had abdominal discomfort (dull ache around the navel area). Every so often I also feel chest discomfort of pain. It is NOT a radiating pain, and it's always the same location. It's a slightly stinging pain but also a bit dull at the same time (I'm aware it's a bit of a contradiction) and sometimes I feel a kind of sinking feeling in my chest.

In general I have difficulty getting to sleep as i just do not feel like going to sleep, even though I may be physically and mentally exhausted. It has gotten worse the past couple weeks and now I just don't know why I won't go to sleep even though I'm barely able to stay awake.

My question, as it were, is there something terribly wrong with me? Something I'm not aware of?
