I notice from your posts in this topic that you are very negative about yourself. The more you do this the less likely things will improve, as harsh as that might sound.
If you genuinely think you have negative traits, think about what you could do to improve them. In my early 20s I was also shy and very low on confidence. I'd just graduated in Computing and got an entry-level job in IT Support - this helped so much as I was forced out of my comfort zone and having to talk to people for most of my 40-hour work weeks. This kinda blended into my personality and while I'm still a bit of an introvert even now, I'm much more open around friends/workmates now, and this also led to me being more confident with dating etc, and I felt better about myself overall as a result.
Everyone's situation is different but maybe there's something similar you could research and look into in terms of jobs or even just social groups. (Obviously right now it's difficult to find either of those things though)
