Just sickly?

I am not really sure what has been up with me.  I just haven't felt good.  Thought maybe I had an infection or fever from a tick bite or I don't know.  Maybe it is just hormonal fluxuation.  Or maybe I am just really tired.  I don't think I've actually had a fever, but felt feverish...sweats and chills.  And then every time I start to go ahead and make the trip to the clinic, I feel a bit better that day and have put it off. 
I have found myself not sleeping right again, not making class and just feeling too tired all the time.  Maybe just lingering, hidden depression.  I know I felt so bad the night before last I was in bed trying to go to sleep and just really had the feeling of not wanting to live anymore.  No suicidal type ideation, but just that tired. 
I guess I am depressed (I think more just over it) because I have applied every where, even places I really don't want to work like McDonald's trying to find a part time job that works with my school schedule and nothing.  I have more things happening at the dance studio now, but it's not enough to pay the bills.  I'm thinking I should have taken a break from school this summer, but it's too late to drop without penalty at this point, so I'm not sure about making that happen.  My cousin's daughter was assaulted spending the night at her best friend's house - the girl's dad tried to pull off her pants while she was sleeping.  I got into a worse discussion with my son's principal and lost my cool - actually losing my grip on polite language.  I'm just done and I guess if I had more than $0.50 I would take a vacation!!
I guess I will go apply for everything other job in this town and see if I can make something happen.  I think breaking free from this level of poverty would probably do wonders for my attitude.  It just lingers and it is beating at me constantly, wearing me down.  Giving another pull up off the boot straps and off I go....
