Tips for dealing with preeclampsia?

I was just diagnosed officially with preeclampsia and referred to a high risk pregnancy clinic. I’m 25 weeks currently, 26 on Monday. Any tips on how to deal with preeclampsia? Diet wise, activity wise? Is there anything I can do to prevent complications with preeclampsia? TYIA for any comments. I just want a healthy baby and myself to be healthy for both my kids. I’m definitely getting my tubes tied during my c section because this pregnancy has been beyond stressful and my first pregnancy also had complications and ended in an emergency c section. My biggest fear is not being around for my children.
