Wow, lots going on, huh?
Bet you couldn't have imagined this time last year that you'd feel the way you do now. That's why anyone reading this who feels like they just can't go on . . . should. Things really do change, and usually for the better. And, sometimes, even a different kind of "shitty" is better than the "shitty" we know until something truly good comes along.
Okay, to your questions . . . all FOUR of them. :p
As for the job interview, I don't think you should stop sending resumes and applying elsewhere. I see you getting more than one offer and being torn by the choice of which job to take. Make sure you're helping to create that situation because it is a good one for you. The interview will go fine and you will be proud of yourself. Remember to shake hands confidently and check the back of your outfit/hair for unsightly-ness and muss.
Career, money, and love . . .
As for career, why do I feel childrens books around you? Specifically well-illustrated ones at that. Hmmm. If you have an artistic streak you should nurture that and let yourself be free to play and make mistakes and grow. I read that it takes seven years to "master" something, so don't be afraid of day one. Now, that could be me responding to the free nature of your question about career - you might be happiest in that arena. Specifically about what you're doing now . . . I think you're going to be much happier in your work around March of next year. "March" keeps coming to me and I'm taking it in the context of the month, not that you need to march away from your job. :)
Money. Listen, it's going to be a case of "keep it simple" for a while. No crystal drinking glasses or luxury vacations for you for the foreseeable future. However, you're going to be happy with the little world you create for yourself. Simple things that make you smile, love them and buy them! Also, talk to your friend Jennie or Jeannine about what she does with her money. I'm laughing, because this could also be a banker you're going to meet when you go check out a bank. Either way, you'll like her.
As for love, I feel like this is going to sound generic because "we've all been there" but this is completely applicable to you:
You can stop being the outsider, the weird kid, the freak and start realizing your uniqueness makes you beautiful. Really, any day now because it's time. You're really a good person with a lovely heart and energy and good people are going to be attracted to you as soon as you can find it within yourself to let your LIFE smile. Make it happen and you'll find yourself surrounded by suitors.
Actually, you need that song. I want you to watch this video.
