I know I don't always suck lol, I have low self-esteem, and I don't have alot of education, and the anxiety has stopped alot of things in terms of career etc, I don't do what many "normal" people do. They have cars, great jobs, money etc, I have my sites, no money, but a roof over my head.
I know it's not good to dwell on the past, but when you feel low it's hard not to think of the things you didn't do or couldn't avoid.
I'm in the same boat as you. I didn't even graduate highschool. I just recently got my GED. My car is sitting out in my driveway with two flats and The exhaust has a massive hole in it and it has an expired inspection sticker on it. I lost my liscense a year ago and still haven't renewed it. I'm a bum!
As for careers ... pfffffft! I have burned all of my bridges. I have left every single job that I have ever had without notice. yep, just up and split.
But, I still don't feel that it is too late. Do you? Well sometimes I do and that really gets me bummed out. But then other times I feel like having a great job really doesn't matter all that much. The money certainly doesn't matter to me. I would like to do something that means something. But you do. Like you said, you have these sites. And I'm sure you have helped more people than you know on these sites. And when you really think about it, isn't that all that matters? Because I mean you can have an awesome job and money hanging out of your you know what

. what are you really
doing with and for that money? Ya know? I think that you are probably more of an asset to the world then say some executive or banker or celebrity. You're contributing to the "whole" if you get me.
I know it's so much easier to just say "don't dwell on the past" than to actually take the advice. I didn't mean it in an all knowing way or anything. I should take my own advice. I kick my self in the ass all the time for the things that I could have done for the things I could have said. For what I could have done to have avoided this and that and the list goes on. But I can't. I only have now. And who knows if I even have next year or two minutes from now. So I just try to stay in the now. Even though I compulsively want to delve into the past and get all riled up. And sometimes I do. Like recently I have been. But I try to talk myself out of it by using the rationale that I just described. I try to "be" there for every moment. Because when you really think about if you're constantly stressing and thinking about the past and future When do you ever actually get to be and live?
lol, Now I'm probably sounding nuts. But this does help me sometimes to think this way. Nothing else really does matter but right now. I mean think about it. There really never is a time that is not now. Ok that sounds weird, but really really think about it.
Anyways, for a woman who says she is uneducated, you seem to have intelligence naturally. Thats something to be proud of. Rather than just regurgitating information that you have learned, you have real life knowledge. Which is pretty damn commendable in my book!
