Help me not die in my sleep, please

So sleep apnea is pretty terrible, but if I can make it through the night without not breathing it may help alleviate some of my other issues, depression etc.

Turns out the machines that will keep me alive at night aren't cheap, so I need a little scratch.

First I have to rent a machine which just cost me $150 and then $40 a week, but that's just short term, because then I'm going to have to buy my own and they run at close to $2k each. 

If you can help in any way it will be very much appreciated. <3
