BobW, first, you are among peers. We are of all ages on this site, from 8 to 90. Many of us are in our 50's. I am well into them. Suicide affects people of every age.
2 weeks into surviving the suicide of a loved one is total shock, total crisis mode. Every cell in your body is reacting to this, and you must drink a ton of water to help flush the shock through your system. Rest is good, and doing what you can, when you can is helpful too.
I am so sorry you lost your brother. Everyone's reaction to the loss of a loved one to suicide is unbearably profound. Our pain is our pain, and we do not feel it less because of anyone else's. So please, don't apologize for feeling. It's the most normal, human, real- and hurtful thing. Becoming a zombie is worse- that happens sometimes too, when coping runs out and we go on overload.
Please make use of this site whenever you want to. It is here for everyone who needs it, and we all support each other.
If I may give some advice, besides drinking water and resting- treat yourself with kid gloves right now. Look for small comforts, and do remember the good things between you and Frank. They are still there. His death cannot take that away. He was doing the best he knew how, he was trying. You love him. A terrible, terrible thing happened to him, and to you and everyone who cared for him, and nothing will ever be the same, but you will learn, slowly- frustratingly slowly, how to adjust. Reaching out is one of the ways. You have found a good place to come and write whenever you need to, and read what others are going through too. Is there also someone you can reach out to- a friend or family member of your wife's maybe, who can help with her care sometimes?
Some people- and often they are men, think they should figure this out and adjust pretty quickly, and then they judge themselves when it doesn't happen. Adjusting to suicide loss does not happen on a schedule. I think it happens in layers and pieces. It's just not orderly at all. I have found myself stepping backwards, sideways, up, down, bent crooked, rolled up in a ball, staring blankly into space, overwhelmed to the point of complete non-function, broken into a million pieces, and once in a while forward. I hope your psychologist proves helpful to you. - You will know. If it's not right, find another, and if you can find a group in your area, that may be helpful too, when you feel ready. Know that most people don't understand this loss and don't know how to act or what to say. It flat out sucks, but it's true.
((((Bob)))) you have every right to be here and to feel what you feel. I am so very sorry you lost your precious, beautiful brother, Frank. You can lean here. All of us do, and somehow we hold each other up.
