FranklinMailot's comment is good advice I think. Getting professional help would be best here.
I also face similar symptoms like how you describe - persistent procrastination with tasks (initiation, or even continuing from where you left).
I faced them since i became an adult through college, and after I started a job. it became pretty clear that there is something seriously off when I underperformed for a good amount of time. Then 2 year ago, I got repetitive panic attacks. Had to take leave for a month. started seeing a psychiatrist.
Then took a test recently, turns out i have Avoidant Personality Disorder. Made a lot of sense, since I struggled with interpersonal relationships - difficulty in getting help from people, more prone to tolerating misbehaviour from other people out of avoidance of conflict, interpreting peoples signs and events naturally in an exaggerated negative fashion thus making me self sabotage etc. I sort of survived through probably because I scraped through when it was dire.
