You have been put on this earth for a reason. There is some reason why God hasn't taken you away. There is something in your future that you have no clue about yet. Be patient.
When you speak with someone, work on getting your mind off of how they're perceiving you. Focus completely on them, on how they're doing, on what they're saying. If someone makes a comment at a meeting that you like, go up afterward and tell them that you liked it, and thank them.
That will plant a positive seed about you in the person's mind. In a simple way, compliment everyone who says something you appreciate.
Everybody likes people who genuinely like them. Everybody appreciates appreciation. Don't be phony--you don't have to gush over people--just give them a simple compliment.
Don't be discouraged if you aren't best friends after you do it once to one person. Make it your practice to care about other people. Then compliment.
If you throw enough spaghetti against the wall, some is eventually going to stick!
Best yet, you'll find that you're not hyper-conscious of your SELF anymore.
