I need advice

I was going out with girlfriend for the past seven months and she's just ended it and im struggling to accept it.

It was only a short time but in that short time we both fell for each other hard.

Its not all been smooth sailing we've had a couple of problems in the seven months and we both bring our fair share of issues.

Our latest problem was last week and this week she ended it. She said its only been seven months and it shouldn't be this hard. I cant disagree with her I understand where she's coming from but it doesn't stop me wanting to beg for another chance though I know it wouldn't help.

Right now I cant stop thinking about her. Everything remi is me of her

I need any advice please
