Input on First Letter to My Birth Mother

I posted this in a different section, but maybe this section should be more appropriate. I am not sure if this is the correct section to put this, but this looks as good as any. I am a couple weeks away from attempting to initiate contact with my birth mother. I was adopted through Catholic Charities in Houston on 1971 and they are facilitating the search and contact attempt. Catholic Charities has a VERY regimented way for contact initiation. So this letter will not be the first thing she ever sees related to my reaching out. She will be contacted with a very bland letter simply stating "we have information we need to discuss with you, please call." When/if she calls CC, they will tell her that her son is seeking contact and go from there. There will be paperwork she fills out and, I think, some pre-contact counselling. THEN, they will give her the letter. Knowing this process is probably why I was more liberal on the amount of information. I am a complete wreck. I have been stuck on my first letter to her for four years. I finally have a draft that I feel pretty good about, but would like to get some feedback from other birth parents. I don't know if she is looking for me or has even thought about me in years. I know what I hope. CC has a very regimented I don't feel 100% comfortable posting this here as it is a little long, but if any birth parents would be willing to look and give me some honest feedback, please let me know and I will PM the letter. Thank you, Jonathan
