Something that has helped me, and may help you, is changing the way you look at things. When I am at my lowest, it really helps to take the things you already do every day and call it self-care. Brushing your hair and teeth. Showering. Eating a meal. Whatever it is for you, try changing how you talk about it with yourself. Taking care of yourself feels good, so try reframing it from things you have to do, into things you want to do.

Also, it's okay to enjoy leisure time. You do not have to be productive 24/7. Doing things that you like and want to do is okay, and it's okay if you put other things off to do those things. It may help you to make a list of all the "productive" things you want to do. Whatever they may be, try and work on one every day. You don't have to finish a task every day, and several tasks may take months or years (getting a degree, buying a car or house, etc). But it feels good taking the first step to do something. Do you need new glasses? Take the first step and make an appointment. Yay, you did something productive!! Breaking things down into manageable pieces really helps.

One last thing. It's easy to fall into the trap of comparing yourself to your peers. Don't. You are on your own journey, they are on theirs. You have had completely different opportunities and circumstances than every single other person on the planet, and you have done the best you can with the knowledge you had to get where you are today. You are doing great, even if it doesn't feel like it right now. Keep trying to do your best every day - and your best isn't the same every day. You got this!
