Advise please, house built in the 1920's

[valleyofthemoon]

We are new to Feng Shui, but believe in the
principles and are trying to learn.
I would like to ask your help:
We purchased a home 2 years ago, that was
built in the 1920's. There is a large lake
nearby, and the area is ringed in
mountains.
We have large Oak trees, there were 4 to
begin with, but due to hazards 2 were
removed(Problems grew more intense when 1st
one was cut it was in the North, and the 2nd
was in the south). The two remaining are
located to the east The largest almost
exactly north-east. The 2nd, to East
directly. Our
Front door points to the North, the rear to
the south.
Since the day we arrived to move in there has
been negativity, in the home, and
outside.
There are things we have done to make peace
with the home. But the inability to sleep,
and all kinds of disturbances keep coming
(marital, money, neighbor, property,
children).
We know little history about the home. We
have heard since we moved in that one
previous resident was mentally ill, and that
the house was partially burned at one time,
but have no proof of this. The lot was
barren when we came except for the Oaks. We
are landscaping with blues and yellows.
Have pointed all bed to the west or north if
west is not possible. The home is very
small(680sq) feet, and square, but situated
on the north-west end of the lot. We have
three children as
well. We would like to have no more
misfortune here, peace and harmony inside and
outside the home. Could go on and on about
the number and variety of things that have
sought us out since we came here of a bad
nature. We can not afford to leave, or sell
at this point in time. We have also had
money troubles we did not have before here,
and the home was in our means when we
purchased it. One more item of note:
The rear 1/2 of the property has a tenant,
but she only disturbs us 1-2 times a year,
although, she seems to have much difficulty
in her life outside the property.
The house number is 118.
Myself: 5-28-66
Husband: 1-25-66
Son#1: 9-29-85
