It's about what YOU want and makes you happy. It sounds like you would prefer to have a few deep friendships rather than a whole lot of superficial friends. Firstly it's about challenging those social pressure style thoughts around we should have a lot of friends and we are losers if we don't when that's not true at all. Cognitive behavioural therapy exercises help with that and Acceptance and Commitment Therapy exercises help with living well with a current situation you aren't fully happy with but will take time to change or resolve.
And if there is some anxiety and depression involved addressing that so that you are more clear in what you want in relation to friendship. It will also help with your feelings around this.
Then you can look at what type of and how many friends you're realistically want.
Unfortunately building friendships does take time and most friendships start off superficial before you go through the steps involved to deepening the friendship. However targeting activities that you really enjoy with people you see on an ongoing regular basis can help you make the type of meaningful friendships you'd like.
