HELP! My whole world is falling apart...

So I was with my partner since I was 16 he 17, (now 31 & 32). He ended things with me last week, cause hes seeing a 21 year old who he works with.

10 days on & my life feels like it's completely upside down, the physical agony I am going through is like nothing I have ever experienced. It's full steam ahead for him and his new girl & it is killing me.

Any idea what I can do to get over this?

I've been signed off work for another 2 weeks & the days are long, but the nights are definitely the most horrendous.

I don't have a lot of friends, the ones I do are mums and have their own relationships and I have never felt so alone.

I'm also freaking out that at 31, I have no children & I'm starting my life all over again & I'm more afraid than ever that im not gonna get what I want.

Im not the most confident in fact, its something I struggle severely with so meeting people & someone to have this with feels like something that's never gonna happen.

Im so broken & I really am struggling 😥
