I started buying again yesterday

I sold all my stocks and took a break for about 4 months.
I started buying again yesterday, but I've already hit the jackpot of negative returns.
I've been trading stocks since 2007,
and looking at my profits and losses over the last 18 years, my cumulative return is only 3% lol.
It felt like they had dropped a lot, so I bought -> made a little profit -> they dropped further, worsening my losses -> unintentionally ended up holding long-term -> received a bonus and averaged down -> sold quickly once I saw a profit after a long time -> then they surged -> regretted it and rebought because they seemed to have dropped a lot.
It's an endless cycle.
My returns are worse than a fixed deposit, but even so, I take breaks from stocks, but I haven't stopped.
