How I'm feeling #2.....

My teenage daughter just recently found out that the dad that she thought was her real adopted her. I told her for the wrong reasons. I wanted to hurt her dad that adopted her & I did know I needed to tell her soon because that had been trying to friend her & I on Facebook. I knew when she was 18 they would tell her if I didn't. I wanted to be the one to tell her. This has blown her world up & has brought the past back again. Her bio dad is still a prick & it's devastating that he still acts like a dumbass. His parents seem great but there's still weirdness & tension & i' ve been told in an email that they don't want the past to be dwelled on. I just brought up that it was weird because of past memories. I'm not constantly bringing up the past if I go visit. I just wanted to explain my feelings but nobody really cares. There house is a house where we lived for a time. I remember things. I never did dope to forget about it & mess up those memories. I also have one of those photographic type memories where past memories appear to me so clear like it just happened yesterday. I hate this about me. My daughter was hoping we'd all get along but it's just not possible. I will always be the bitch that terminated their sons rights. My husband will always be the one that came in& took the option of their son being a dad away. I am pissed about this. If the grandparents really wanted to know what was really goin on, they could have called me during this situation or tried to talk to me. There's even a law for grandparents that if they wanted to be involved, they could have taken it to court. This is not my fault that their son lied, turned out to be an ass & always will be. I have felt so much guilt around them about this but I have to let it go so I can move on. I have done what I thought was best for my daughter even though most of the ex's family feel otherwise. At the time this was going on, I was pulled by so many people, feelings, etc. All in my 20's. My daughter is very bright & was diagnosed w/ADHD at the age of 5. She had been doing very well w/o Meds & since this has come up it's like it has come back. She can't remember anything, grades are dropping, & she's turned into a rebellious teen again. I am struggling w/ what to do. I support her education but feel it's not supported by the ex's family as they all have quit school & a GED is about as far as any have gone. I want her to go to college. She has great potential. I don't wish my life on her. Low income sucks. Working manual labor sucks. I could have went to college but chose my ex & was burned badly from it. I can also blame my parents for it as well because they didn't encourage my love for art & for me to do art, i would have had to go to a college away from home. They didn't ever explain to me that that wasn't possible due to finances. I'm now stuck in this rut of a life. I did used to love what I do but due to how people treat people generally, I have lost it. I can't physically handle this job forever either. So then, what will I do?
