I live alone. It depends on whether you are safe, and if you feel comfortable. If you are just unsure of yourself, you might get used to living alone. If you aren't comfortable, that's ok.
I would suggest looking for a roommate that doesn't have epilepsy. If it makes you more comfortable to have someone with epilepsy that's ok, and it could work great. On the other hand it might also add stress to your life. That doesn't mean that people with epilepsy are a "burden". It's just that you may be maxed out already. If your epilepsy got worse when you moved out, you may be struggling with things. What you need is peace and security. Whoever you room with should help with that.
Some people will have problems with epilepsy, others will be fine. You will be able to tell by their reaction. I never had a problem with a roommate. I HAVE had problems with other people, but not a roommate. I mostly found roommates that were people I already knew. Some I didn't know very well, but they were in my larger "circle" of people. There were few I got "stuck" with didn't go very well for other reasons, but not because of epilepsy. (I went to college a lot.)
My suggestion would be to let people know you are looking, but don't necessarily "advertise". Look for someone that you already feel comfortable with. When you bring up epilepsy be sure to be specific. Most people don't have a clue what it means. They only know what they saw on some film in elementary school, or on HOUSE. For example, I don't know what your epilepsy is like. Most people will be concerned with "what they should do", or how it will affect them. Avoid giving in to the feeling that you need to over explain or be apologetic, if you feel that way. Just tell them what they should know as an equal partner. Remember that it's ok if someone isn't comfortable with it because then you will know that it's probably better not to room with them. It doesn't mean you can't be friends.
