HI there everyone,

I"m new here and reading through some of the posts I've found what I need. A place to discuss these things which cannot be talked about anywhere else literally since nobody understands. 

So I have 3kids of my own and 1 SD, been married for 6 years to DH, but we've known eachother for 10. SD is 16 now almost 17 and since it's summer vaca she spends weeks with us. Here's the issue.....while she is polite when she does speak, she barely speaks to me. A bit more to my kids but very minimal. She lies or sts in her bed literally all day and is on her computer or phone. She barely gets  up to eat (that's a whole other discussion). I've stopped asking if she wants to join me and my kids on our outings because the answer is always "no". She doesn't seem to have any hobbies or doesn't want to do anything. When she is with her mom, she does a bit more I think and she has her friends there.

I'm feeling that she can't stand being around us, I could be wrong, but I feel the distance. She gets moody. I don't know if she is really depressed, or just can't stand life when we are around or when she is with us. 

LIke I said I"ve stopped asking and talking because it doesn't lead to anything. In the past she would occasionally join us but all that has drastically changed. She seems happier when DH is around (he works out of the house but has flexibility). I work from home now due to Covid. He sometimes takes a day off to take her out and "talk" to her bc she "feels uncomfortable talking at home". What they talk about idk...... I know he wants her fulltime, college, etc but I never hear the results of these talks. 

I could go on, but I'll leave it at this for now. Just trying to navigate this loooooongg summer. Normally, when I'm out working and my kids are out at camp we don't witness all this, but since this year is different......

thank you
