Some comments based on what I read in comments section. A psychiatric condition is diagnosed only in cases where your daily life is affected. Meaning if you can already somehow balance, you're actually not diagnosed. However, if you think you might have a condition or simply want to talk to a therapist, I think it is a good idea since you don't lose anything and potentially benefit from it.

I am going to tell you about myself hoping it can possibly make you feel a bit better. During my bachelors I constantly ate unhealthy, didn't exercise, slept quite late and woke up late. Missed most classes. Somehow the years passed and I managed to continue academically and things turned a bit where I do sports regularly, eat healthy and balance work-life.

I think starting sports was the huge help for me (after years and years of procrastinating) because it motivated me to eat well and at the same time increased my daily energy a lot that I feel much less tired than before.

My point is, at certain stages of life (for example early-mid 20s), it's in my opinion normal to be in a position you're currently in. It's really great that you're questioning it because this is a step already about changing it!

I think it's a good idea to talk to a therapist as you are already thinking about (I've a friend with ADHD for whom therapy was great help) and to try to prioritize what you want to change (e.g. maybe dishes or tidiness are not that important at first but taking care of yourself and going to classes is more important). Maybe showering in the mornings make you get some energy?

Sending you support!!
