First things first....
I've enjoyed the art and story before, I look forward to doing so again.
People who use the quote "Tis better to have loved and lost than not to love at all" are either one of two things. Unknowing sacks of sentimentality or fellow sufferers.
I've had breakups. Good ones and bad ones. I actually don't have the dubious honor of being "just friends" with any of my ex's. The women in my past are either gone to the wind or added to the list of THEY WHO SHALL NOT BE NAMED.
Repeating "Time heals all wounds" is overused. It doesn't help when you look at that little "nothing" gift that "THEY" gave you and you start feeling all those bad feelings again. People trying to cheer you up can HELP... but it get's annoying sometimes.... Sometimes you just WANT to feel bad...
Suffice to say, I know the situation. Been there, wrote a book, buried the damn thing.
You have an outlet. Making the comic must have been a good release for you (plus a decent reason to cry for a few minutes and get it out of your system for a bit)
I think you'll do well expressing yourself in comics. Keep it up.
And just so you know... It never get's better. It get's DIFFERANT. If you let it, the feelings you feel now will STAY. But you seem WAY too strong to let a situation control you for long. You can't control what the world gives you. But you do control YOU. From what I'm reading, you aren't just sitting around WAITING for life to give you things. Moving locations, changing who and what affect your life, all give you differant options and input. There will be new people to meet, interact with, and with a lovely fun person like yourself, to love. I'm sure of it.
Good luck Milady.
