My advice would be reach out to those friends that you miss, and dont be too hard on yourself for not maintaining a lot of friendships. Sometimes friends are only supposed to be there temporarily, but sometimes you meet an absolute gem of a person where you have a great friendship but life just gets in the way and you drift apart. It's just a weird life thing, I'm sure the people who you actually miss would love to hear from you. Send them a meme that reminds you of them or a joke you had or just send a msg saying hey (right now with everything going on it's a good excuse to reach out to people and check in, it doesnt have to be awkward or weird I've reached out to a few people I've lost touch with just to say hi hope you're ok and weve picked up the thread like we just spoke yesterday.Yeah it’s rit! I’m just not sure how you make and maintain friendships these days ... I had a great group of friends at work but I’ve switched jobs and we kinda lost touch! I’m sure things will get better though!
Or if you want to make some new friends, think of something you're passionate about if it's to do with your career or even a hobby and find an online community and make friends on there to build up your confidence
