/vent sort of/looking for advice/ 

I've had anxiety since I was very young. I'm now 20 and barely leave the house since having a baby. It seems my anxiety has worsened the more I stay inside. (But these symptoms have ALWAYS been a thing) it seems I get SEVERE anxiety anytime I have plans. Way before rhe plans actually start. Dr appt? Anxious. Concert or something I'm really excited about? Anxious. Social situation within a week? Anxious. Basically any plans I make good or bad make me super anxious and I don't understand why. Because unless it's a social situation it's not the event itself I'm afraid of so idk why I'm so anxious for a concert that I'm excited about. (Really bad social anxiety too) because I'll go the entire day wanting to throw up from anxiety but get to the concert and be perfectly fine and have fun. Man I just wanna chill and enjoy my time before events wtf. Does anyone have insight as to why this could be or does anyone else have this kind of anxiety too? Maybe there's something else I'm subconsciously anxious about that I don't realize or maybe it is just anticipation anxiety and my body just doesn't understand there's no threat. Idk but I just wanna chill for once. Is there any anxiety med that could help with this kind or would it just have to be worked on in therapy? I'm so worried that I'll be suffering this kind of anxiety from events for the rest of my life.
