Will my energy come back

Yes both nervous afraid to sleep and racing thoughts about having panic attacks. Also afraid to sleep because I keep thinking I won't wake up because of how the physical syptoms keep me worried. Plus stressed. My mind in general is so foggy and no peace at all. So I've been suffering a bit of insomnia the past month

I am sleeping for 10 hours a night and still my energy levels are low.. it's just the anxiety, you can get as much sleep as you want and still feel low
