some grunch:

I like the suggestion of changing things a little at a time.

Your girlfriend misconstrued your remark. Clear it up by
telling her you'd like to move closer to her. Make sure
she understands your remark was not because you have the hots for
a closer look-alike girlfriend. We've all hurt the ones
we love. The good relationships persevere.

My contribution to the din:

What is your diet like ?? Someone with these types
of problems ( emotional swings and outbursts, depression, sleep
difficulties, weight gain ) probably eats terribly.

Too much caffeine and sugar probably for starters.

Get the book "Fit for Life" by Harvey and Marilyn Diamond.
It's the Bible for fixing food issues.

Meanwhile, I recommend:

Reduce the caffeine and sugar intact as much as possible.
Eliminate as much cheese and dairy stuff as possible.
More fresh fruits.
More fresh salads.
Less pigging out.

See if that doesn't help the sleep and emotional discipline.
