Hi Alison.
6 months is not a long time so please be gentle with yourself grief is a roller coaster ride and a long journey. I found when i was on my own i longed for company and when it had company i wanted to be on my own -its difficult to find a balance but you will.
It has been seven years for me and i am doing much better -learning to be alone and at least content with your own company rather than being lonely does take a long time -and still when i leave work on a friday i,m not rushing out of the door knowing that the weekend will be spent in all liklihood without speaking to another person (except whatsapp calls with my daughters/grandkids.)
My solution was to make friday night treat night -bath with candles, bit of chocolate -whatever a treat is for you -and that did take the sting out a bit -Its really silly because of the nature of my job when i,m at work i can also go all day barely speaking but i guess its knowing there are other people around that makes a diffference.
Despite that still occuring feeling of dread, i am usually fine once i get home -When the weather allows gardening can completely absorb me -and you are never really alone when there is wildlife around (yes i am that rather dotty old lady that talks too the birds) but i realise that isnt the solution for everyone, other people will find new interests,perhaps new social groups but it does all take time.
Coming here knowing that everyone understands because all of us are at some stage of our grieveing, having some-where to write what you cannot find the words to say out loud to some-one,and even just somewhere to have that daily chat -"how was your day", "Is this a good idea" "what do you think of" is in itself is something we miss so much although written rather than spoken and answers not instant, it does help.
When i first came here i wondered why a bereavement forum could have a laughing emojie -yet it gets used a lot because laughter is important too and something else we miss, even though it seems there is little to laugh about.
