Hello,
I'm so sorry to hear of your losses. It is still very early days for you in this horrible time. I am around the same age as you and also came here after losing my mum on October 2017. I lost my dad in 1985. I know how difficult it is to lose your mum and dad. It's unlike any other loss really, as you suddenly find yourself to be the older generation and lose that lifetime link you've always relied on to anchor and support you in life. It must have been even harder for you being so far away from your mum and dad. So awful to have lost a brother in such a terrible way too. I am so sorry.
I hope you get the counselling you have requested. In the meantime, all I can do is tell you what kind of things have helped me. I think you have to do whatever helps you. In my case, it was just little things at first, like taking walks in the park, putting flowers round the house as I found they cheered me up a little bit, they are so pretty to look at. I found it easy to forget to eat and drink properly so you should make sure you do that. Sleep is a problem too, so try reading before you go to sleep or taking a relaxing bath, having a milky drink, just whatever works for you. Cry when you need to and just do whatever helps.
Take it one day at a time and don't push yourself to 'move on'. Grief takes forever to come to terms with. You don't really get over it as you probably already know, you just learn to live with it in time and gradually the bad memories lessen and the good ones become clearer.
It sounds like you had as good a farewell to your mum and dad as you could have done in the circumstances, and you clearly did whatever you could to help them as they got older, so take comfort in that. Hopefully, your husband will help you through this too.
I found it helped to try to do something each week that would take me out of myself, got me out of the house and made me think about something else for a few hours, so you might try to find something that will help you to do that. Grief is exhausting and drains you, so its good to have something that distracts you from it a little for a spell.
In the early days I also found it helpful to put together an album of favourite photos of my mum and to keep a diary, so I could write down how I was feeling and what I was thinking. It was a kind of release to do that and then later you can look back and see what progress you've made as time has passed.
Other than that, use this forum to write down how you feel and you will always find someone to listen. The Facebook forum is always active with someone ready to respond with some sympathy or helpful suggestions. You might also try the chat room in the evenings. All useful to help you find support and help you feel you are not alone in struggling through this difficult time. I am sure you will get a few more answers from people with better suggestions and experiences to relate and recommend than me, but hope some of this helps.
Thinking of you and sending much love and hugs...Take care, Hun. Join in any chat whenever you like, whether here or on the Facebook Group. You'll always find someone around to respond. All best wishes...xx
