Hang in there. I think you are doing a great job if you are joining clubs and putting yourself out there. Keep smiling, talking, leaving your door open, getting involved and you will make the connections you desire.
I have only one other thing to add…because of technology I think today’s youth have a hard time with alone time. Kids today are always plugged in and always connected to others via social media, texting, snapchat etc. Because of this, I think people have a hard time being alone. I think many have not learned the skill of being alone for any amount of time. Remember, some amount of time alone is normal. You can’t possibly with others every second of the day.
