Your subconscious acts in tandem with your conscious mind, each affecting the other. Your conscious mind (thinking) can be trained, and the subconscious will follow—but it does take work.
Thinking sad, worried and frightened thoughts all day long does you no good at all, obviously.
I wonder whether you have any absorbing hobby or interest you enjoy and that would take your mind off your troubles? If not, affirmations are the only way, and they definitely take work/self-discipline.
The kinds of things you're telling us here are not helpful. Assuming they're representative of what you're thinking all day every day, they'll keep you stuck and unhappy.
Time to turn the ship around, Captain!
