I haven’t experienced what you’re describing. Previous experience suggests exposure is the next step for you. If a cooking class isn’t feasible right now then start with watching some videos online (best if they’re home cooks - you want to watch common cooking of foods you like to eat).

You’re not trying to memorize anything or learn hard skills during this time. You’re only trying to become more familiar with people working in a kitchen so it doesn’t feel as alien and maybe not quite as scary.

Do that regularly for a while. If it’s too much for you: dial it back. You do want to push your boundaries but only when you’re feeling ok about it. Small wins will turn into more small wins and eventually you might be interested in trying to cook something.

If that happens, and I suspect it will, know that it is OK to start cautiously and take your time learning how to use the oven and stove top. Try turning a burner on with no pan or pot on top. Let it get hot. Turn it off. Let it cool down. Repeat that across a few days if the first one helps you.

Once you’re comfortable you should do that practice again and add water to a pan until its half full. Once the burner is hot: place your pan of water on top of the stove burner. Let the water come to a boil. Remove the pan from the stove top. Let the pan and water cool down. Note how much water is missing (some of it will have steamed away while boiling). Add that much water back to the pan and practice this again.

You can build your experiences, step by step, with safe extensions and new footholds, until you’re feeling confident about cooking something with the boiling water. You’re going to boil an egg!

Complete your practice again but instead of taking the water off right after it boils: leave it on the burner for 6 minutes. Then remove it and let it cool. Success? Do that again using a pot instead of a pan. Pot half full of water. Grab a serving spoon or similar item. Once the water comes to a boil:

1. Lower the burner temperature to half / medium. The water should be moving and steamy but the bubbles should be very gentle or cease. Dropping the egg into actively boiling water may cause the egg to crack prematurely.
2. Use the serving spoon to gently place the egg in the center of the boiling water.
3. Wait six minutes.
4. Remove the pot of water from the burner.
5. Turn the burner off.
6. Use the serving spoon to lift the egg out of the hot water.
7. Run the egg under cold water (this helps it from over cooking and helps make peeling easier).
8. Enjoy your egg.

You can absolutely boil any kind of pasta, lots of vegetables, and almost all starchy foods. Boiling is very safe because the water regulates the temperature for us. So long as there is water in the pot the pot is unable to meaningfully exceed 100 degrees Celsius (the boiling point of water / ~212F). It is very difficult to burn anything or start a fire while boiling water.

Best of luck my friend.
