Do you also have these “mental traps”?

I've been investing for one year, so I consider myself a newbie. I completed a 3-month course on investing and decided to go all in. So far, I’m up 20% on my trial-and-error portfolio. What I’ve noticed through this process is that I'm extremely irrational—yeah, I said it out loud…

• It's hard for me to invest in my targeted positions when my stocks are going up (for example, Rocket Lab recently). I
• I prefer to add to my positions only during dips; I just can't make myself stick to dollar-cost averaging. I have monthly allocated cash to invest, which I keep aside earning 5% interest until I see a dip.
• I'm unhappy when the market goes up because I feel I “missed” the chance to buy at lower prices companies on my watchlist.
• The bigger the sum in my investment account, the more nervous I feel about “recessions” and “corrections.”

From my point of view, these are all mental traps. Does anyone else experience this, or is it just my mind playing tricks on me? How can I get rid of these feelings?

p.s.: I’m open to any feedback, but please be kind in your comments. I'm already feeling like I am an idiot
