I to lost my Husband on 15/11/2014 but it still at raw as if it was yerserday, our girls where only 1 and 5.
To be honest I never seeked out Professional help but instead found great comfort in a friend I became close to while my husband was sick and now we are Best friends.
In my case it wasn't the fact of having professional help or not but the ability to have someone who I could be open and honest with, and not feel judged or pushed into doing things, or Grieve in a manner that other people wanted me to.
She was and still is the reason I was able to try and find the strength to go on without my beloved husband of 20 years.
What I'm saying is, you do what's right for you, either professional help or not, but the most important thing is to talk, let out your grief, anger, dismay or whatever you have inside, don't bottle it up, take time to express everything inside.
In my case in my case I built a 20 foot tree house in my back garden, repainted, redecorated, dismantled the tree house as it didn't have planning permission
Took up Tae Kwon Do again, went to the Gym etc you get my point?
But I spent the past 2 and a half years not keeping anything inside and at the same time making sure my two girls didn't miss out.
Yes of course I also had bouts of depression and uncontrollably crying but in the end it all helped me.
Sorry it's a bit of a long post, but please express yourself how you want, you will feel a part of the burden slowly lift.
I hope this helps
