need advice on anxiety

I'm 31 weeks pregnant and for most of my pregnancy I've had a real problem leaving the house myself or attending pre-natal classes myself really anything that involves being around people I have looked into this being a case of social anxiety and some of my symptoms do point to this I'm just wondering if anyone out their feels this way to and if so what it is? before I fell pregnant I was out going loved meeting new people basically the opposite to what I am now and I don't want this to be something that's long term as that will effect me taking my child into social situations😣
