Letter to a Lover, From a Mama's Boy

[almonds]

Well, BW BRINE, bless you and your heartaches;
Tried to help you mate.

I’m waiting for the holiday to amplify my mood;
the change is taking longer than it should.
And even though your relatives are having lots of fun,
I am not feeling even slightly good.                                      - This line sounds quite awkward and not in harmony with the previous three;
                                                                                               'even slightly' does not sound fitting well here. Perhaps change the line to 
                                                                                               'I happen not to feel all that good.'
The Christmas tree is glowing with a headache-causing hue.                 ^
The cookies have way too much cinnamon.                                          Works quite well to me.
And every time aunt Lisa laughs I feel like I will die;                              
her voice, to me, is a carcinogen.                                                          v

I chose to leave this letter so you would know where I am;    - Could work well without the 'would', with only one past tense, since the next line 
I wouldn’t ever want you to feel blue.                                       repeats it
Forgive me - I’m a coward - and I don’t deserve your love.
Please tell aunt Lisa that it’s her not you.

Maybe there is something wrong with me.
There’s a decent chance I won’t recover.                      - Is the second 'there is / there's' necessary? 'A decent' maybe? Also, this line seems a 
Just like all the other men who failed to carry on,           bit too short
I will go back home to live with mother.                       - I think without the 'home' it sounds better and more fluid.
