Welcome ..we have found you and we have heard you and we are here for you.
I am so proud you have reached out today to get some support and I am also happy you have taken on some of the words of your missus and jumped on here to share and to let us sit with you. This is not an easy thing to do and so I wanted to say "well done" for not only sharing how you are feeling with her but also with us too.
A GP appointment is a great place to start, there are also the support services that Sophie_M has given you as well. Maybe jot them on a piece of paper and have them handy as it is sometimes hard to remember what to do or how to find support when you are feeling so very bad.
What I would really like to do is beg you to stay, for your partner and for your kids...but I will not do that as while they are a very important reason to stay, the most important reason is YOU. Life sounds hard for you at the moment with little to motivate you or to look forward to, with feelings of hopelessness and feeling so very worthless, I am so sorry you are feeling like this. I don't know how you are feeling and all I can offer you is my virtual arm to sit and to listen and for you to know how much I care and that you can share things here if you would like to. To get them off your chest.
You may not know the answer to this question and it is perfectly ok if not but do you recognize any of the triggers that happen in a day that perhaps make things worse? Are they thoughts? Are they people? Once again it is fine if you do not know but being able to find a few of these out might help and I would like to chat to you about that if you would like to.
I would also like to tell you about the Beyond Now app and I will put a link here for you:
If you wanted to get this app and maybe even sit with your partner and do it with her and get some things in place for you when you are feeling so dark. Not only can you address the things that might work for you in helping you get through that moment but it could help her to know too, and also to know what is NOT helpful.
I am a family member of a person who took their life and I never thought that when someone said to me "it is hard now but it will get easier" that that would ever be true. I can say that while it hurts each day it does get easier to manage. There will be brighter days Norts and I would like to chat more to you, if you would like to.
