am I wrong?

First a back story! I've had two ectopics the first one I had to have a forced abortion and the second one I almost died from and than 7 months ago I had a natural miscarriage but have had no luck getting pregnant again! So with that said on to my rant if that's what you want to call it. I got invited to a baby shower for one of my brothers friend. Well this chick is a known drug addict and I'm talking about shooting up heroine. she has had her other kid taken away, she just got out of jail for stealing, and has numerous b&e; charges. She actually found she was pregnant while she was in jail and since than has been back 7 times, failed several drug test with her p.o. When they invited me to her baby shower I declined nicely but than everyone started pressuring talking about please noone is coming the baby did nothing wrong and so on. I eventually snapped and I told them the truth I cannot be happy for someone who is pregnant who clearly does not care. this would be around the time I would be having my baby shower and its just to hard to watch someone be celebrated for being pregnant when I don't feel like they deserve it. I'm finally at a good place and going would just set me back in my depression. She litterally has not cared at all about being pregnant until it came time for the baby shower. NOW I'm the bad person and I'm being petty and7 I need to just get over it already. So now I have completely cut everybody out including my family who joined in on the its been long enough. honesmtly I'm to the point to where I don't care I have my husband and thats all I need! sorry this was long just needed to get it off my chest because I don't get it!
