Starting weightlifting?

[martinanonymous]

I'm thinking about starting to lift weights, but I'm worried that I'm going to do something wrong and will injure myself. When I mentioned it to my primary care physician, he said that it's really important to do so only under the direction of someone who really knows what she/he is doing and that one needs to lift really light weights very, very

If you were able to do knee pushups, you'd probably be able to work your way up to regular pushups eventually. The strain on your wrists is pretty similar in either position. It's great that you're going to see a professional regarding your wrists, I'm sure that will be really helpful in developing a repertoire of exercises that won't be harmful to your body.
Like industrialdoom said below, there are pull up bars you can buy that just hang in the doorframe and don't require any mounting or hole drilling. I know you're on a tight budget, but maybe it's something you could save up for? I believe they're around $30 or less and there's a big variety of exercises you can use them for, not just pull ups. I'd definitely recommend checking out some body weight exercise forums as there are lots of things you can do with conventional household items that you may not have considered.
I know that for myself, working out regularly has been a key element in lessening my depression and increasing my overall happiness and confidence levels. I hope you're able to get a plan going for yourself with help from your physical therapist.
