I feel like a loner

So I love being by myself and I’m usually so content by myself, but lately I’ve been feeling like I’m always just sitting in my room. If I’m not in my room I’m doing errands, but still by myself. I have good friends I’m just never the one to ask to hang out but they don’t ask really either. I don’t know what to do I feel embarrassed bc people know I’m always just by myself and they probably think I’m lazy and doing nothing
