Everything will just float on from here- or will it?

I've made one of the biggest decisions in my life so far by putting my two weeks in at my current job. I've been at this job for almost 3 years now and if you knew me well enough, you'd know that I  definitely ignored the risk and took the chance. See, I've always defaulted on having this job because it's been the only way that I know how to stay normal. I've been able to live off this job and for the past three years I've been depending on it. Before I couldn't fathom leaving it because it's really important to me that I depend less and less on others and more on myself. However, I've been convinced lately that a little help may not hurt so bad. In this sense, I could look past the risk and see myself happier down the road. It's so scary and in a ways I'm very stressed out, but at the same time I've never known a feeling like this. I feel like now that I won't have a job, (though there is a new job I hope to get that I have an interview for this week) I have to potential to live any way I'd like. At least until the money runs out lol. But I feel like this could push me towards something new, something better. And that in itself makes this all worth it. Now, I am just very worried currently about posting a few weeks in the future dreading this decision. But now that I've made it a point, I'll probably just avoid this situation at all costs, and make sure that I never have to feel such a way. I need this new job I might get. I mean, it'll be a different change of pace than what I'm used to. And what I'm used to is ...chaos -_- But I think I can do this new change!! I mean...it's retail and I've always wanted to get into that job field. I know I can adjust. I just need to be given the chance to prove myself!!
