Help - Masturbation to feel grounded

Hello,
Please help, thank you in advance.
This is both a health/relationship issue I guess.

To give you a bit of background I have recently split with my girlfriend after 2/3 years, we had a healthy sexual relationship, sex was regular.Lovely girl, I will miss her, but I ended it because I didn't see a future in us and I didn't want to string her along. ( I thought long and hard about this and we did try to fix things)

I was looking forward to being single and working on developing myself and my carear but since becoming single my sex drive/testosterone levels have been through the roof, so much so I'm finding it hard to concentrate and I'm not thinking clearly or working hard.As soon as I masturbate I think rationally again and I become more productive and I feel "grounded", I don't want to have to do this all the time it's not feasible, does anyone have any advice? Will anything else have the same/similar affect on me?Any suggestions?

Thanks again in advance.
God bless
