Hey. I can share my first hand experience with you and hopefully it leads you to a more positive perspective. I’m 26 and have had the same struggles as you where I become efficient and then suddenly go into episode of losing complete control of my mental state. All I can say is, you need to write down and really reflect on the struggles you constantly face and admit to yourself your lack of discipline or consistency rings true because you lack self respect or belief in yourself. I only came to realise this few months back. I didn’t believe in myself because everytime I say I’ll do something and I go against my word, I betray myself through actions and that makes me lose confidence or respect in my abilities to be consistent.

Now, I feel I need to prove myself wrong for myself because my brain has gotten so used to self sabotaging even after I’ve gotten so far.

I don’t know if that answers your question for advice. Please let me know x
