Certain people bring certain things out of you. Also, you need to learn to love yourself before you proceed with anyone else

I used to be just like that. Fortunately over time I got better at holding conversations, developed a good sense of humor, and somehow gained self confidence. It seems like it's just something you grow into, some people later than others. If you make a genuine effort to be friendlier and lighter spirited it will happen.

NOT you complaining about **** like this while having a BOYFRIEND LIKE

Be yourself at all times. Being yourself will put so many other things into place in your life, trust me.

find someone quiet like you. There are plenty of people out there that have the same personality traits as you, trust me. Yall can be quiet together

None of those things equate to having a trash personality. I'm sure there are plenty resources online about projecting confidence. Until then fake it - put yourself in situations outside of your comfort zone (where possible) and see what happens. Doing this builds confidence and jabs away at anxiety.
