Exercise: It may seem impossible to get motivated, but you don't need motivation. Don't even bother probing your feelings. Anxiety commonly causes depression, which in turn causes people to feel they are not enjoying thing and will not enjoy things even if they try them. The trick is to do it anyways. Keep it up for months. Try to keep your heart rate elevated for 30 minutes a day. If you fail or are physically tired or sore and cannot do it just accept you are human. Failure is a normal part of life. Try to made exercise a habit. It is not easy, but many people report exercise at the main and best cure for the depression part of anxiety. That can help you sleep better and that will help with feeling tense.
Might try cutting caffeine and stimulants out of your diet and try to not overeat or eat unhealthy foods. Try to avoid taking sleeping pills or other aids to make you feel sleepy. This can help occasionally, but if you are taking them several times a week or multiple nights in a row you are probably only hurting yourself in the long run. Drink a lot of water to help with exercise and avoid headaches.
Look for tips on improving sleep.
Maybe trying making a time to write down you worries (plan for a time to worry and then try to only worry each day during that time), that works for some people.
Mindfulness has proven to help many people with anxiety.

Anxiety sucks. I suggest not resorting to long-term drug use, as there are probably healthier way to deal with it. But even then, drugs are probably better then living with anxiety for years.
