Is anyone there for me,please?

Just had to end a relationship with bf of 3 years due to ongoing issues,some MH ones on his part. I stuck it out hoping and hoping that things would get better,but after one too many circular arguments I had to let go. I've no family or close friends to turn to and I feel absolutely distraught. I thought I'd feel relieved but I can't even bear the thought of having to start over at 50. He has now blocked all contact which I know is right,as despite everything,the pain would have had me contacting him again. I'm having panic attacks and cant stop crying. I feel like I'm going to die of heartbreak,even though I know it wasn't right for either of us.All I can think is could i have done more.

You have done what you could. You have made the right decision.
You will be ok, just that you will go through a tough time. You won't die of heartbreak.

50 is still young. You have about 35 yrs ahead of you.

I'm here for you and feel something very similar. It hurts so much. You will start to feel better even though it doesn't feel like that just now.
Getting through the next minute then hour is the key. One day at a time. Try to get some fresh air if you can and look after yourself: shower, eat something avoid drinking.
You can do this x

My mum met the absolute love of her life at 55!

It sounds like you made the right decision no matter how much it hurts. Well done!! That takes courage.

Be kind to yourself. Practice self care. There will be good days and bad days but things will get better for you

I'm in the same position at the moment. It's been 2 weeks with no contact.
We were only together 18 months, but it hurts like hell! I'm hoping he will text or call, but at the same time I know I'll cave in and go back. Stay strong!
Try putting some up beat music on, read a book or watch a funny film. I try anything to keep busy. The pain won't last forever... I promise
