I am beyond stressed?!

I am beyond stressed?

It may not seem like a real problem to anyone, but I am so stressed out, I have been looking for a summer job because my regular job is cut off during the summer, which means I have no income coming in, I have my last final tomorrow, and have no money, my head is hurting so bad right now, because I can't relax, I have a thing for always having it together, but lately it feels as if everything is falling apart, I don't know if I would be considered as having OCD or if I am just extremely stressed, I have this money problem which is the main cause of my stress, but I need to relax, please help me with some suggestions of relaxation.

Please no childlike suggestions.

You just hang in there. Take your final tomorrow and concentrate on that tonight. Your headache is probably from stress, but have you eaten a decent meal today? Had a lot of sugar and junk foods? Will certainly give me headaches. How much sleep have you had recently? Up studying a lot?
Get as much sleep as you can, eat well tomorrow, and take your tests. You'll be fine. You know you can't live tomorrow tonight, so just take life one step at a time.

I don't think you sound like you have OCD, just worried about things. Everybody does that. If they haven't yet, they will if they live long enough.

About your job, why don't you start working on that after your tests tomorrow? Things have a way of working out and most of what you worry about in life never happens anyway. And if it does, it's not usually as big as you had thought it would be. A job will present itself soon, I imagine. Check where you can for a summer job and ask around. Talk to a counselor. Put a smile on when you get scared. Have a little faith and something will turn up and you will be ok. I wish you the best.
