You deserve that highrise. Go for it, maybe not so close to your daughter.
I am glad you don't have to worry about her finances now. You truly need to destress so you can get healthy. I have a few tips that may or may not help a bit.
1. Say a prayer of gratitude every day. I read that having a gratitude journal helps ones mental health. Try it??!
2. Meditate! I use guided meditations from YouTube and sometimes I even fall asleep during them but I always feel better afterward. Calmer. Meditation calms your mind. I like spiritual meditations.
3. Stop, for your sake, being angry at daughter's boyfriend. He isn't all that bad...could be worse. He can deal with her and doesn't strike her. You said he has empathy. He isn't a criminal or drug abuser. Let him go. He is not worth your health. He may not be who you think your daughter should be with, but he isn't going to harm her. And the wrong man WOULD hit her. He seems harmless. That's important.
4. Take nature walks every day. Notice the birds, the smell of grass, the breeze, the sky. Being music if you like.
5. If you don't feel up to it and if the kitchen is dirty....wait to clean it up until you feel up to doing it, even if it's the next day. There is no rush. Get rest first if you need it. The house doesn't have to be done NOW...when you are not feeling your best. There is plenty of time!
If you can turn back to your husband, date him, have fun together. My husband and I have been doing this. It's fun!
Light and lots of love and good health! Your health first!
