I need advice

I have been so stressed for this past month. I tried to fix a bunch of things but it’d always come back after a day or two. I had a trip with my mother and sister to relax. I was able to very briefly, but now I feel like something is missing. I feel so detached from everything. I started thinking more negatively for some reason (trying not to) and the days started to feel repetitive and bland. Without my mom in the house I feel even more this way. I am closest to her and even my conversations with her feel fake and bland. I love everyone so much, my friends, and family, I just want to go back. I am trying to find out how. I tried to indulge in my hobbies a bit while also writing about how I’m feeling. Like poetry, drawing, calling friends. But I’m always just left scrolling through social media and watching videos. I want to stop this. And I also never feel the need to talk to my sister. Because sometimes she just annoys me. Every time she comes to talk to me it’s always about her. It’s not like I want it to be about me but everytime i walk into the room to talk to her she’s doing some activity for herself. I just don’t feel the need. I don’t know if this is affecting me but I feel even lonelier. I feel drained and I lethargic. I wish I could go outside and meet my friends in real life, but all our schedules are different. I looked in the mirror and thought my skin was getting darker which I immediately related to diabetes. I got a bit anxious and then stopped after realizing it was probably just lighting. I started dieting and I worry if I’m eating too much or too little. I even thought I had an ED but my therapist and I eventually talked it over as general anxiety. I get worried time to time about it. I plan what I eat and perhaps that is stressing me out. This feeling is horrible to me. Usually I feel relaxed and content, but I feel restless. Is there anything else I can do to target this? Like picking up new hobbies?
