I am in my late 20s. I used to be quite popular at school- not in a cliquey way, I just had lots of friends in different groups and found it easy to talk to people. All throughout school I found it easy to talk to people and have never been particularly anxious about social situations or doing new things.
When I went to university I had a massive knock, I suddenly found myself very out of my depth. I went to a university where I high proportion of people were from private schools and were very self-assured and had opportunities that I could never dream of.
Since university I have muddled along with a few jobs and then gone back to re-train in a career with good prospects. I have met lots of people along the way and have really tried to be sociable (I am an introvert so can have a tendency to be happy on my own). I send messages to people suggesting that we meet up and either get ignored (when I can see that they have received the message) or get "yes! I would love to meet up for a coffee" but then can never pin them down to a date. Or even worse, arrange to meet and then a few hours before get a text cancelling with something like "I'm really sorry but it's my friend's birthday tonight and I promised I would go out".
I have offered too to make myself useful to people- offers of babysitting to friends who are parents, offers to help with chores to people who have newborns, offers to help with decorating to friends who are feeling overwhelmed in doing up their new house.
I'm tempted just to stop bothering as it feels very one-sided but then am aware that I will end up friendless. Am I doing something wrong? Is offering to help people creepy? I'm having a bit of a crisis of confidence.
