It sound like you are struggling with “shoulds.” You feel like you “should” be able to figure everything out on your own. In your original post you stated you need advice on even the smallest things but then when you gave examples later, all of those things were pretty big.
In fact, they were things that most people would ask for advice on or talk out with someone.
Sounds to me like it would be helpful for you to ask for advice more often and then pay attention to how your friends actually react rather than how you worry they will react. You’re telling yourself a mean story about yourself. It is very possible that your friends feel good about you asking for their advice. People like to be useful 🙂
