The only advice I can give with handling loss is recognize the primary and secondary feelings:
Distant -> numb, withdrawn
Frustrated -> annoyed
Bitter -> indignant, violated
Humiliated -> disrespected, ridiculed
Let down -> betrayed, resentful
Lonely -> isolated, abandoned
Despair -> grief, powerless
Guilt -> ashamed, remorseful
Depressed -> inferior, empty
Hurt -> embarrassed, disappointed
You may feel many secondary emotions at once ie powerless, disappointed, remorseful and resentful. Traced to the primary emotion, we get Sad and Angry ....let yourself be sad and angry - sit with it for awhile...don't explain it or try to reason it, just sit with it and recognize it....emotions are the body's alert system - simple as that
Once you recognize the emotion be mindful that you choose how to react to them like if I get stressed, I feel bad and sometimes recognize the anger....if I stay in denial, I will snap at people being annoyed by the smallest thing then feel sad (guilt) afterward especially if they weren't the ones that caused the stress. When I realize it I focus my self talk to "THINK":
T: Is it True?
H: Is it Helpful?
I: Is it important?
N: is it necessary?
K: is it kind?
Often I withdraw and focus on getting the energy out redirecting it to something positive like tearing a room apart to deep clean and rearrange it until I am exhausted....sometimes there is yelling, sometimes tears, sometimes beating the shit out of my carpet with a broom etc. In this way, I don't unnecessarily take the stress and anger out on those around me and able to let go of that emotion. Once I am done, I can then redirect my energy to what I can do about it.....the anger and sometimes sadness comes back when there is nothing I can do to resolve it - there is frequently another room to dismantle though sometimes its beneficial to get out of the space and into a more positive environment like taking a walk with nature letting thoughts wander and just be
