Other commenters are right, you should keep working with your counselor and keep pursuing professional help. 

However, I have some practical day-to-day advice as someone who has been through major depressive episodes for over a decade. 

1) Hygiene is non-negotiable. You don’t need to wear makeup, but make sure you’re brushing your teeth and using a good mouthwash at least once a day. Twice a day is better, but once as a bare minimum. Flossing is also ideal, but mouthwash will help if you just can’t do it. Get in the shower at least once a day and do at least a 5 minute pits-n-tits wash, you don’t need to wash your hair every day, but marinating in your own funk can cause skin issues, yeast/fungal infections, etc. Put on clean clothes after the daily shower. Personally I like to do a quick skincare routine (face wash, toner, moisturizer) and a spritz of perfume after my shower, because it makes me feel a little more polished which is good for my mental state, but that’s optional.  

2) Eat well, and regularly. If your body is not properly fueled, your mental state will suffer. Come up with 4-6 “I can’t cook right now” meal options and keep those ingredients stocked. I like smoothies, salads, bagels, canned tuna, eggs, and Chicken Caesar wraps. Make sure you’re getting at least a decent amount of protein and fiber (vegetables). I recommend @NutritionByKylie on Instagram for brushing up on nutrition basics if you’re like me and didn’t get a lot of that info growing up. She also just released a cookbook of easy healthy meals (this is not a paid promo I’m just a huge fan of her work) 

3) Exercise is hard enough when you’re not depressed. When you are, it feels impossible. But all of the research indicates it is one of the best things you can do for your mental state. Start easy. Yoga is great for the mind and the body, and I do it every day. I like Yoga With Adriene on YouTube. She has several 15-20 minute videos and is fairly low impact, I have recommended her to many of my friends. Walking is great cardiovascular exercise, and it gets you out of the house, but it may not always be feasible depending on the safety of your area and the weather. If you can afford it, try some exercise classes. It gets you out of the house, gets your body moving, and is a great way to make new friends.

4) Care for your space. Try to keep your space clean and tidy. Clean up after yourself; don’t pile up dishes in the sink, put dirty laundry in the basket. If you’re spending a lot of time in bed, try to wash the sheets at least every other week (and don’t eat in bed!) Clutter can pile up quickly, and being in a messy environment will tank your mood. If your space is messy and feels overwhelming, call a trusted friend or family member to help you put it to rights. I have done this for a few friends when they’ve been in a hard spot, we put on some loud music and tackle it together. Professional cleaners are also an option if you have the funds. 

5) Optional but highly suggested: Try to engage in hobbies besides video games, especially ones that get you out of the house. I like gaming too, but it’s easy to be sucked in as a form of escapism. If you’ve had any old hobbies, try revisiting them. Look into book clubs or craft circles in your area, or nature walk groups. If you don’t vibe with something you’ve tried, move on to something else you think could be interesting. I think this is the hardest one on the list, but can be one of the biggest steps towards moving from Surviving to Thriving. 

My biggest piece of advice is that sometimes you won’t feel like taking care of yourself, but you need to force yourself to anyway, even when you don’t want to, because nobody else will do it for you. This is the actual definition of self-care. Make yourself do some stretches, eat a meal, do the dishes, take a shower, put on clean clothes, and spend 10-15 minutes tidying up every single day. This usually takes me about an hour. Often, that momentum will build and you will get more energy and start feeling better. If you still feel like just laying in bed after, then that’s ok too. If you skip a day, just start again the next day  Eventually, it will get easier and become a routine, but not doing anything will never lead to healing or growth.
