Hi Peri2022. Sorry to hear that you are suffering, but you're not alone and I'm sure you'll find lots of good advice here.
Have you tried EFT (tapping)? It was recommended on the forum recently and I've found it really helpful. I think you can still do a free trial on the Tapping Solution app (I found it so helpful I have taken out a years subscription). I know that I have some deep seated issues that I need to address and plan to find a therapist to work through them with (rather than just an app), but if I'm in a total state some of the exercises help calm me enough to get through the day (although I might need to do them a few times). There are also loads of videos on Youtube to get you started.
Another recommendation from the forum I've found useful is the 'Therapy in a nutshell' channel on youtube. There are some excellent practical videos on dealing with stress, anxiety, panic attacks, emotional distress, etc.. Finally, another free app recommended here recently is Insight Timer - Jennifer Piercy has some excellent meditations for helping with sleep - I find getting a good night's sleep is a massive help.
After many years of living in flats, I'm lucky enough to have a garden now, and spending time outside is something that helps ground me a bit, even when the weather is grotty. It is frustrating that it takes so long to find the right balance of solutions, but hopefully things will start to improve for you. Good luck.
