You have plenty of company.
My trading account is one-sixth the value it was 18 months ago and two thirds of it is gone forever even if TSLA hits ATH again. There are many reasons why, but the biggest reasons are stupidity and options.
It does suck. I was leveraged to get most of it back, but after Q1 earnings I feared a trip down to 100 again and unloaded large amounts waiting for a lower price to load up again. There were other factors at play, but all of it is my fault. The account is still 10X where it started once upon a time, so I should just STFU.
Hang in there. I cannot tell you to simply load up again and count your profits in a couple of years. Risk is still a thing, and whenever I have done this the past eighteen months I have paid dearly for it (of course, if you avoid all leverage and cannot be margin called, then it may be an option you could sleep at night with. Sell some when you need money and otherwise let it ride). There still seems to be a recession coming and where car stocks will go when it finally arrives could be perilous. And no matter how bulletproof Tesla suddenly appears, there will be trying times again, probably sooner than we think.
