However, it could be a vibrational change if you're meditating frequently (also an abuse of white-gold energy in your aura, which makes one more alone). And, if you're meditating, your vibration is changing, and it is tuning with the life you're headed, the life you're creating.
When you're advancing and get to higher states of being, people that don't match your energy will just leave, because friendships are formed between people within the same vibrational state, who have the same purpose and idealogies in life, and while we're elevating ourselves, very few people match with us, that's why this is mostly an alone path.
However, if you feel the need to have more friends, and you need more socializing in your life, you can do workings for it. Workings to attract more friends, relationships and so on. You can use the WUNJO rune to get your old friendships back and EHWAZ to attract new and stronger ones.
