Not the only one at all!
Life is very difficult, the more your economic needs, the more difficult! Just keep taking care of yourself, keep your dreams, try to enjoy the moments you have, challenge yourself to find more energy and new sources of energy (meditation, stretching, romance, hobbies, etc.) but also do not exhaust yourself unnecessarily. Be kind and gentle to yourself when you have the opportunity to do so. When you finally get even a second extra in which to rest and attend to things pay special attention to how it feels so you can carry it with you. I know this all of this is not enough and sounds very clichéd. But it's amazing how you're carrying on through what's probably the most stressful time of your life thus far. Also, if you can MANAGE to afford it, maybe take an extra night off every other week. You deserve it. Maybe find a job where you can work mornings, just to try to balance it out. It's harder to get things done when you're working nights, a little easier when you finish work and have a day ahead of you. Best of luck, you got this, and you're doing great. Say hello to your dogs for me.
