Im in a state what do i do?

I lived a very sheltered life for the past 20 years. My childhood was great, as soon as I hit middle school I was bullied endlessly, im very shy to start with so I just shut everyone out. I had a few friends but I never kept them after school. At college it was good but again I could never let anyone in, was always quiet and never went out partying with them, it was never my thing.
The first time I got a bit tipsy I was happy the day after cause I felt like I know could say id been drunk? I could tick it off the list? And so people wouldn't judge me.

After college I worked with my family, still do and its what I want to do. I have one school friend who I got on well with but she has her own mates. I started doing something, going swimming every week, I met a lad and I did like him but he wasn't interested so we keep in touch as mates now.
Im feeling alone though, im happy as me, and im happy with my life. but my mum is very controlling, im 21. And one day she came to talk to me about 'boys' at this point I was going on an odd date with a lad but wasn't interested, my mum asked me everything about it, and told me I have to try and it will take me a while to fall for him blah blah.. but I wasn't interested at all... she kept going on and on about my life. I barely go out drinking, I go to the gym, swimming, to classes I have interests in to meet people. Never having a boyfriend makes me feel awful. Who will want me? I feel like im letting my parents down endlessly. I thought one day id just click with someone, ive been on dates and liked guys so that must mean im trying? My mum seems to think I need to go out and get started but I just dont want too?
Is that bad? or normal?
