Yes - absolutely - you definitely want to come up with something that will be good for you to use for a long time to come...
If I may suggest - a name that is about who you are can be a good approach; however, a name that is about what you are going through - or anything else that might change over time - is very highly not recommended. Consider leaving the "in the moment" pattern of thinking and search for something that is more in the 'big picture' of things - something that represents you in a more larger-than-life sense rather than in an in-the-now sense.
And, of course - yes - it should fit well into this environment.
I hope you come up with a really good one!
(I have no doubt that you will - after you have thought about it for a while...)
