Be nicer to yourself. You're still learning.
We are currently in a pandemic and no, you are not getting left behind. Don't be too hard on yourself. Don't push yourself too much. Take a breath and relax. It's okay to be unproductive and it's also okay to do all the things you need to do. It's okay to feel scared of what could go wrong and it's also okay to think about what could go right if you will do it. Despite how hard it is for you, continue to heal. Continue to do things. Continue to grow at your own pace. Continue to learn. Don't rush. Take care of yourself. Head up, everything will be okay. Never give up.
