It may seem hard but no matter what, You Can Do this!! As long as you stay focussed you will get there.
Like Nelson Mandela once said:
It always seems impossible until it's done
So even though you feel like you can't do it anymore, whatever it is (working out, relationship with your partner, finances, business) what's important is going through the motions.
Just keep doing, just keep going, and just keep moving and eventually you will win.
