feel like im loosing it

You need to call the doctor prescribed the Lexapro and tell him what is going on. This could be a side-effect or an escalation in your symptoms. Either way, you probably need another medication, possibly a more specialized anti-anxiety medication. Just don't stop taking the medication without first talking to your doctor and seeing what he says.

If the doctor you're seeing isn't a psychiatrist, you need to go see one instead of just a regular doctor. It sounds like your symptoms are severe enough that you need more specialized treatment.

As for tips on how to leave the house, I wish I could just tell you everything is going to be fine and have your anxiety go away, but I don't know if anything I could say would help. If you do think you are able to go out, make sure there is someone with you that you trust, like a family member or friend who can help you and take you home if you have an anxiety attack.

I wish you all the best. I hope you find relief soon.
