Pregnant FTM with social anxiety disorder, how do I make friends?

I find making friends a daunting experience. I’ve moved to a new country 5 years ago and have only made a 2 friends and one doesn’t talk to me anymore (had a bad argument) and the other is 70 years old and I don’t make time to visit her... she’s like a grandma figure to me since all my family are back in my home country. Anyway I don’t expect the 70 year old to call me much.

This pregnancy is so lonely. I really just have my husband and I’m wanting to make a few friends. How do I take things from aquaintance level to actual friendship?

There’s this girl at work who’s pregnant. She’s due one month later than me. Previously our conversation went as far as hi and bye. Now she makes an effort to ask how my pregnancy going and I ask how hers is going. Thing is, I don’t have time to hold long conversations at work as my job is soooooo busy and fast paced so our conversations are short and to the point.

I really like her as a person and I want to make friends with her outside of work, but how the hell do I do it? Will it be weird if I ask for her number or fb? I feel desperate doing that, but I am desperate to make friends. I feel sorta iffy having friends from work too bc what if we have an argument of some sort and I still would have to see her.

I’m in my late 20s but I still feel like a child when it comes to making friends. 😩
