Life can feel extremely overwhelming at times, and I'm so sorry you are feeling that way now. I have been there many times. What has helped me most is knowing that I can do things to make myself feel better. Instead of feeling like everything is out of my control, I know that there are something's that will make me feel better in the long or short run if I embrace them. Take some deep breaths, and try to focus on what you can do to solve the problem instead of solely focusing on it. I have had trouble sleeping my entire life because of my anxiety, so I had to change a lot of things to make it better. I now have a set bedtime routine that starts after I take my melatonin. I dim the lights, play rain sounds, and get ready for bed. When I am feeling down, I try to do things that I know will make me feel better in the long run. Like getting 10-30 minutes of sunshine, doing a 15-30 minute workout, playing video games with my friends, or calling up a loved one.
