Ok firstly you are not a loser and there's nothing to hate yourself over!
Secondly, after five very sedentary years, yes, you will need to start at a "pre beginner" level. Fifteen crunches? Good heavens. That definitely IS a tall order when one is 290 pounds! Simply getting down onto the floor and getting back up again could make me break a sweat at 245 (and is still depressingly awkward at 229)! Crunches, ha! Start at "attempting to do ONE set of ONE" or don't even do them at all right now. There are other things you can do that may be more comfortable and just as helpful. Go for a walk, for example. Just get outside and walk up and down the block. Walk up a flight of stairs. Do it twice.
A possibly good idea, though potentially costly, would be to hire a personal trainer. Now I know what you're thinking - fitness trainer? aren't those for athletes? But in fact no! A good personal trainer can help you set some goals that are reasonable and achievable for a person at whatever stage of health, fitness and ability they are at. Or maybe wander through the Fitness forums here on Spark; I'm sure there are plenty of people with plenty of tips and stories of how they started adding activity to their lives. You are certainly not alone here! Lots have walked or are currently walking in exactly your shoes.
Me, for now, I have to admit, I have NOT been adding a lot of formal exercise activity to my life. I'm aiming for "a walk" each day. GOOD ENOUGH for now. Instead I am focusing on the healthy eating/portion control aspect of this weight loss journey - and without having done one single crunch, i'm down 16# since Jan 9. I feel better about myself and less uncomfortable when doing certain tasks such as bending over to tie my runners or climbing a flight of stairs. I am actually starting to feel like i WANT to move around a bit more...
Be patient with yourself. It is what it is, accept it without judging yourself so harshly, "this is where i am, and today i am taking one step towards over there where i am going."
