I guess this has somewhat to do with the constant ongoing identity crisis borderliners face; I get bored of EVERYTHING that's not a 100 % exciting all the time. This goes with every aspect of my life: my job, studies, hobbies, my partner, my friends, my life style and routines, my appearance. I find something interesting and go all in until I hit some kind of obstacle, I don't see any radical development or I just become... bored. Luckily, I don't lash out on my partner, family or friends any longer just because I get frustrated, so that's a good thing. But now instead I turn it inwards and walk around like an living ball of anxiety and self-hatred. I am smart enough to stay away from heavier drugs, but I do have a tendency to drink - no super large amounts, but just enough to cope with being bored and feeling meaningless. I work part time, which in itself is good because it stops me from becoming obsessed with whether or not I am doing good enough at work, and my partner works full time - this results in me mostly sitting around at home, not taking a shower or taking constant naps when I'm not overeating. This is also extremely frustrating because I feel like if I was 'normal' I would probably either a) be completely content with just dicking around at home by myself or b) get it together and do something productive. But I can't force myself to any productiveness (like cleaning, taking a walk, or even getting dressed), yet I am repulsed and feel guilty when I look around and see my home and myself falling apart both physically and mentally. Anybody else like me, or anyone have any useful thoughts/affirmations/ideas on how to change? Change in both the area of me having a problem starting things up, and regarding me also struggling with keeping interest in things for a longer time than like a month. It's daunting to me because since I obviously have constant racing thoughts, I feel like I have all this capacity (even though I'm not something extraordinary) but have no clue how to use it in a constructive way.

EDIT: Yes, I do also have a coexistent ADHD-diagnosis with strong tendencies of impulsivity.
