Do we have a chance? (long)

We just became licensed to be foster parents in the state of Illinois about four months ago. We have been waiting on a placement since then and was thinking about doing a domestic infant adoption. But we have some concerns that I thought I would ask you guys and see what you think. I have depression in which I take medication to maintain. I have been in therapy and would be able to get a doctors statement stating that I am well and have been stable for a long time. So that is a concern. Do adoption agencys frown on this. Also another major concern is would we be a "marketable" couple. I have a masters in professional counseling and my husband has a BA in computer Science. He works for the USDA and I am a social worker. The thing that concerns me is our weight. My husband had the lap band surgery and has lost a total of 107 pounds. He is doing really well and we are working out and eating healthy. I also am overweight(275). We are both very healthy and are working on losing more weight. No health problems at all. We are 30yrs old. Have any of you had concerns that you wouldnt be "chosen" because of these issues. You can give it to me straight. Thanks in advance for the advice.
