Hi Ricky and welcome
As a father, I can feel some of the pain. I have a couple of amazing kids, but we lost one soon after birth just over 12 years ago. He had an underdeveloped lung and was born prematurely due to medical complications with the wife. I remember us sitting next to his incubator, and the doctor coming in and telling us that he doesnt know if we are religious but if we are, we need to start praying. I had remained strong throughout for my wife, however at this point, I just fell apart. I prayed harder than I have ever done in my life, and when he left us, we just fell apart. We went through some really rough times, although I appreciate the difference is that he never left the hospital so we never formed that close bond that you do with your kids as you watch them grow, but I can understand the feeling of helplessness and guilt, even if the guilt isnt justified.
I suffer from PTSD at the moment, for a different reason which I still havent had the guts to go into on here, but PTSD, anxiety and depression do go hand in hand. Brain fog, frustration, anger, and then boucing straight into tears and feeling completely helpless all go hand in hand together. How did we get over it? We never have, we just deal with it, occassionally a memory will hit us, and we deal with that then. She has dealt with it differently to me, I dealt with it differently to her, but I have learnt something really important which I recognised to be a massive stumbling block, then, after his death, and now, dealing with unrelated PTSD, anxiety, depression and panic/anxiety attacks. If I can offer you one piece of advice, it took me a very long time to realise this, but STOP, and LISTEN to your body. One of the biggest mistakes I made was believing that as a man, I can handle anything and everything and that I am invincible. It took two breakdowns, and crying constantly day in and day out, panic attacks, and my body basically failing me to realise that I am not invincible, noone is, everyone has a breaking point and it sounds like you are close to it.
Listen to your body and mind, be kind to the fact that you are tired, emotionally, psychologically and physically, and dont do what I did - keep on fighting through everything because, as a man, thats what we do.
If you dont mind me asking, do you and your wife have quite an honest relationship? I find that writing a letter to mine helps massively as she doesnt feel threatened by me talking to her face to face, and she has time to process it without the feeling of being threatened.
Welcome to this forum - this has been a real rock for me in the times of my moments of weakness.
