I already have two kids- and they are a big part of my inspiration for wanting to improve myself. I do worry about them being influenced by my problems, and I'm not sure if it's my influence, or genetics or whatever, but my son seems to have autism- I am taking him to a specialist. He has problems focusing and staying on task in school- and he prefers to keep to himself, but doesn't shy away from others when they talk to him. My daughter on the other hand is extremely social, loves interacting with other people, has no qualms about saying hello to everyone she sees, I just hope that I don't cause her to lose that as she gets older- cause sometimes I have discouraged her in certain situations- like she sees a teacher she knows from school at the supermarket, wants to go say hi, and I'm like "No, we don't have to" but usually she's already run up to the person, and then I'm a little awkward feeling like I should say something- I don't know, maybe this is actually a good thing to have a child that is the complete opposite of me socially- I could actually learn from her.
It is tough, but I think that it is a rewarding experience, and can actually force you to get involved in things that you otherwise wouldn't. My case is a little tougher being divorced- and I do worry about their dad's influence as well- he loves them and tries to be great with them, but he is bi-polar and has periods of extreme self-loathing and low self-esteem and feels like he doesn't deserve the kids- oh well, the point is no one is perfect- and you shouldn't let your emotional problems keep you from experiencing something great like parenthood- because honestly, no parent is perfect and probably has issues of their own- emotional or otherwise- that have a potential influence on their kids. The thing is to stop worrying about it or over-analyzing it, and just do the best you can.
