Train signaling help

In the attached image, you can see my current train (rails) setup. How I got to this point? Don't ask (haha). But, whatever I try I can't seem to get the blocking signals to behave. I keeps telling me that a station is either impossible to reach due to the signals or the signal loops into itself.

I've almost lost all hope this is even possible. How can I fix this so both trains are able to ride and don't collide with each other? The trains don't stop at the same stations so sometimes they just have to wait and that's fine by me at this point.
