You may have been on this long enough now that simply stopping it is not a good idea; that's called a "cold turkey" withdrawal and it's a shock to the system.
Have a read through this, though keep in mind that you may not need to spend a very long time tapering off if you've only been taking it 3 months:

Benzo withdrawal symptoms are usually temporary things which fade over time, but it can take quite a while, even after relatively short-term use.
If you've been taking 1mg per day, you might want to try something like: cutting to 0.75mg for 2 weeks, then to 0.5, then to 0.25, then to 0.125, then stop taking it. That would be going "fast" compared to what the Ashton literature at the link I posted suggests, however, since you have only been on it for a short time, it might not make sense to spend 6 months tapering off.
Really what you should do is discuss this situation with a doctor who has a lot of direct experience withdrawing people from benzodiazepines, but that can be difficult.
Some people are able to just stop benzos cold without too much trouble, but if you've only been off for a day and you're already seeing some problems, you may not be one of them. Klonopin has a half-life of 30 hours, which means that it generally takes at least 3-4 days for the full withdrawal effects to manifest.
I am sorry you are dealing with this. If it makes you feel any better, I to0k 2mg per day for many years, and I was able to withdraw completely. It was not easy, though.
