What’s the best thing to do ?

Hey Guys.

For the past 2 months I have felt down with my life and I have been though a lot within the last 2 years everything from losing a loved one to being happy I was starting my own family to miscarriage and then my bf walk g out on me and the fact I have to see him all the time doesn’t help as I do want to be with him etc. To losing my job due to covid 19 and not been able to go out anywhere as everything is closed due to covid 19 as well.

I don’t really have any friends I can relay on as there all in relationships and have there own family’s

I feel so down and lonely nothing really makes me happy anymore I feel stuck like there’s no point in anything that it doesn’t matter what I try I’m still going to be unhappy and lonely like nothings going to change

What’s the best thing to do / best person to speak to regarding this ?
