This is so sad actually. All this just brings back a memory I don't really want to remember. I lost my old friend some years back, he had issues with his wife to be.
There was a little argument about finances, and since women are sensitive she woke up the next day and said she doesn't think he's the one anymore, she wasn't sure about him anymore. She felt he was trying to control her finances but all he wanted was to give her advice to spend her money wisely and not get into debt. She was his best friend for about 5 years, surely messed up here and there, if not all the time but he would always apologies and take blame. I remember her saying she felt she wasn't a priority to him anymore, but I know she was.
That day started like any other day, he called me early in the morning saying he couldn't sleep, as usual I listened and listened. Everyday I listened. We got off the phone, I tried to call him after I arrived at the office, no answer!
A few days before he had given her set of keys to his apartment to me, I remember driving to his place after a few unanswered calls, I found a note saying "I tried to show her she meant the world to me. I lost my mother just last year ago, and she didn't support me. She only cared about her feelings and lost me in the process, now I am taking care of myself" his body in the bathtub, boy a few weeks later depression hit me so hard, I could've done way more than I had done for him.
A few months after his passing she got hold of me on Facebook, we met for coffee, I showed her the note and she broke down right there. She blames herself to this day for his actions, he gave up a little too early.
OP, there is a point to everything, people will give you advice but it is up to you to take that advice. Whenever I feel like this, I normally go somewhere I can throw stones or just scream, we all need it every now and then. Something I have suggested to my SO, we have a date in September for some screams and rock tossing. Stupid but it has helped me over the years, find something that will help you, something you enjoy doing!
