I can relate to feeling like nobody is really there for you. It is hard to make genuine adult friendships. My friends are busy with their own lives. If i msg someone, they will give me a one word response or not really hang around as long as i want.
My mum was my best friend and i think i missed out on making quality friendships growing up. Its been several years since she passed but I still struggle. Some days are harder than others but i try to accept that this is the way of grief.
