It could be that you truly are too restless to meditate right now, but that's okay because there are other things you can do to work your way there.
1) You can focus on performing positive actions: be kind and helpful to people, be generous, give donations (even if they're small) to Buddhist temples, and save animals which will otherwise be killed (release fish into the river/ocean, etc.). The Buddhist answer why you are suffering now is that it is due to bad karma which you accumulated in previous lifetimes. You can eventually purify this bad karma by accumulating good karma.
You should also avoid harming other beings whenever possible (this includes insects!), and becoming a vegetarian is often a very good thing to do.
You can also get a Buddha statue or print out some beautiful Buddhist images from the internet to hang on your walls to inspire you. Even if you don't have an altar, you can imagine that you are mentally offering flowers, treasures, and other beautiful and precious things to the Buddhas and Bodhisattvas. They, of course, don't need any of this, but it creates good karma for yourself.
2) You could do yoga or other exercises. If you're too restless to meditate, then a "moving meditation" like yoga might be better for you. Ashtanga yoga is one of the most physically intense styles of yoga, so if you want to work out some energy in a spiritual way, that might help you.
Or physical exercise can be helpful such as walking, running, swimming, bicycling, hiking, lifting weights, etc. They often improve your mind as well as your body. See if your mind wanders while you're in the middle of doing heavy bench presses!
3) You could recite the Refuge Prayer. Once I went to the lectures of a great Tibetan Buddhist yogi and one person in the audience asked him what he should do when he experienced frightening, hell-like states of mind as an after-effect of using drugs for a long time. The Buddhist yogi advised this person to recite the Refuge Prayer and possibly the long version of it (I'm not sure what the "long version" is).
Here are some of the short ones:Traditional Refuge Prayers
I go for refuge to the Buddha,
I go for refuge to the Dharma,
I go for refuge to the Sangha.
or, the Tibetan (Mahayana) version:
Until I am enlightened,
I go for refuge to the Buddha, Dharma and Sangha.
Through the virtue I create by practising giving and the other perfections,
may I become a Buddha to benefit all sentient beings. http://viewonbuddhism.org/refuge.html
You could also go to your nearest Buddhist temple and go through the taking refuge ceremony to formally become a Buddhist. You can do this at a temple of any Buddhist sect. You can still learn from any sect of Buddhism after doing this. For example, you could take refuge with a Zen Buddhist priest and then later decide to study Theravada or Tibetan Buddhism.
4) Limit your exposure to forms of electronic entertainment. You said that you have a problem with your mind racing all the time. Watching TV and surfing the internet certainly don't help this. Go back to the basics: exercise, read, listen to the sounds of nature (or of the city). This can also be a preliminary way to calm your mind down, so you might be able to meditate later.
I hope you are successful in overcoming your problems.
