Forget about the difference between tropical or sidereal for now. Determine the aspectual strength in virupas on the moon from any planets.
These are based on degrees not signs. Example, yes, Mars may aspect the 7th and 8th away, but really that means he aspects between 180-210 degrees with full 60/60 virupas.
Those start to decrease gradually beyond 210, but it can still be there. All planets have these exact aspectual strengths.
If Saturn, Mars or a Malefic Mercury aspect Moon it can show where one's difficulty comes from. If Moon is WITH malefic Mercury, or Moon is Waning or with Rahu/Ketu can give those kinds of difficulties indicated by the planets.
PS- I'm not used to reading western style charts, and I don't see a Ketu in that chart, but if your Rahu is where it is said to be, then you've got a kala sarpa yoga happening which explains a lot, without even looking at exact aspects.
And if I'm reading that chart right, Rahu is in the first?
