Hi, coraliesolange,
I'm sorry to hear about your father's passing. It sounds like a very stressful time for you.
A lot of us have learned to repress our own emotions. That is how we survived a childhood with a parent who had overwhelming emotional needs. We needed to put our own feelings aside because it wasn't safe to share them honestly. When we become adults, it can be difficult to learn to get in touch with our feelings, which is an important part of Remembering (look at the Survivor's Guide--->. While we didn't have a choice about the abuse we suffered as kids, and we developed understandable coping mechanisms as a result, now that we are grown we do have a choice. We can start to challenge the patterns ingrained in us and learn new tools. Working with a therapist can really help.
How can someone be so selfish to take away their child's time to grieve? Ugh.
It sounds like you would like your mother to have some empathy for what you are feeling, maybe comfort you and let you grieve. There is nothing wrong with needing understanding and comfort at a time like this. Do you think your mother is capable of seeing and meeting your needs? Is this something she knows how to do?
The thing about grief is, everyone does it differently and at their own time, and the process isn't always completely linear. Right now maybe you are still experiencing some denial about the loss of your father (Stage 1 of the Kubler-Ross model). A lot of people feel kind of numb during this stage. I honestly think it is a pretty common response. So is anger (Stage 2). Right now your anger seems primarily directed at your mother, which may feel comfortable to you. You also seem a little angry at yourself for not having the emotions you think you should be having at the time you think you should be having them.
You seem concerned that you might have an uncontrollable flood of emotions at some unpredictable and inconvenient point in the future. That is certainly a possibility. You seem anxious about it, and that's ok. Sometimes it helps to examine our fears and make a plan for those situations we are anxious about. What if you do burst into tears at work one day? What bad things will happen--will you really be "ruined" if you have feelings? What can you do to take care of yourself if you suddenly feel sad? I'll bet you can find a way to give yourself the care and compassion you need.
I think rebl.brown had a good suggestion about support groups. Grief counseling (either individual or group) can be really helpful at a time like this. It can even help just to talk about it with other people who have lost a parent. Hearing what other people experienced can feel validating. Maybe you even have a colleague or two at work who has been through this; perhaps they'd even have a referral to a good grief counselor. It's something to think about.
Wishing you peace,
PF
