Dealing with COVID-19 aftermath and other health issues

I've had covid twice and the first time (about 7 months ago) mostly I lost my taste and smell and I'm still waiting for it to return. The second time (a few weeks ago) I had and am still having issues with weakness, tingling, fatigue, tinnitus, and other seemingly neurological issues. I'm looking for a way to heal this issues the best I can or at least learn to deal with them. The latter is particularly issues are particularly difficult to adjust to. I also have sexual dysfunction because of my testicular surgery, am looking for motivational help with my ADHD (around eating better and following through on everyday tasks), and am curious about naturopathic treatments as well as hyperbaric oxegen therapy. If any of this relates to you, please message me.
