They know what is what but they dont know what is what they just strut. WHAT THE FUCK...?

So I realise now I seem to post on here when i'm stuck and I don't know what to do. Well it's happened again.
I don't know what the fuck to do.
I really fucking don't.
I've just came back off a night shift, one which I could have cried so many times but held back the tears as I had to.
My problems at the moment in life: (May not seem a big deal to anyone reading but they are to me)
+ The Navy. I have minus days to decide. Some people are making me try the training in January. Others are persuading me not to. I have no real opinion on the matter. I really cannot decide.
+ I'd love to go into the relationship side but theres a one million chance to one that it might get read by the wrong person as much as I need to get it off my chest.
+Bude. I've had an offer of a place to stay somewhere not in Bude, for free until I find my feet. This could be the opportunity to get out of here, but again, it would be taking me back to my old ways which I know how much I hated it, but right now seem tempting.
+My mental health. I can feel it breaking down, not into a depression, but to schizophrenia. It's so fucked up beyond anything I can explain.
+Karma. I can't help but think that I'm doing eveything wrong and thats why bad things are happening to me. I try so hard to be good.
+My future. Where does it lie and what the fuck am I supposed to do?

I've got so many choices and I cannot logically work out what will be best for me.
I have no motivation anymore to do anything, I feel literally stuck with no way out and I know thats not true, I honestly know I could do something about it all but I just feel i'm not capable.

I want someone to tell me what to do. I NEED someone to tell me what to do because i'm clueless.

For 3 months now i've been on a permanent high, so happy, really happy, infact, i've had probably the best 3 months of my life. Now i've stopped to think. And thats when everything hits me.

There is so much advice I would give to a person who wrote this. It's a shame I can't use it for myself.

What am I supposed to do???
