I feel like my friends don't like me. Should I talk to them?

So I went to university this year and discovered the social anxiety I thought I had conquered in high school was still very much there and has gotten worse.

Besides struggling to make friends, I have begun to feel my few friends from high school don't like me/ want to phase me out. I hardly get texts from them and only get invited out every so often from the group chat. I also feel like they are uncomfortable around me and talk behind my back.

Should I tell them that I'm pretty depressed and anxious about this, or keep it to myself?
