What helped me is outsourcing the administrative stuff (book-keeping, taxes) to an accountant and forcing myself to meet with him once per month physically, best is to make an appointment a month ahead. Insisting on the physical meeting is a trick to force myself at least once in a month to prepare for the meeting (getting all the documents together, travel receipts, invoices, letters). It costs a lot of money but it is worth it for me.
The next trick has a similar pattern: find somebody to spend talking time on a regular basis, at least once per week. Not necessarily a therapist, but a friend, partner, colleague with whom share some common interests. Then force to keep those talking meetings. This helps, because you can talk about your anxiety, talk about what new things you have found, etc. I do it with a friend on a weekly basis and with a psycho-analyst at least once per week - if I don't travel.
The third trick I discovered only lately when being under huge pressure, in a situation in which I didn't know a way out: I started writing as a form of talking to myself. It worked best by "switching off the screen", i.e. typing without seeing what you type (either by literally switching off the screen, or by putting the font to same color as background - I made color scheme mode Vim), it gives you an additional motivation to re-read it later. When I first discovered this, it felt later like magic. I use this trick only when under big pressure - didn't make it to a habit, yet.
Maybe this advice helps.
I wish you to find a way to cope with your life and get to a situation where you can have a decent and more stable life, but still learn new stuff. Good luck.
