How do I get my spark back?

Before I dated this guy for 6 months, I felt vibrant, confident, and charismatic, totally in love with who I am. I tried dating this male friend but it was emotionally draining. I even got a rash from the guy. A close friend told me I had “lost my aura” and that’s when I knew I had to finally end things. It’s been 2 months later and I’m still feeling so low and not like who I was. I know I’m a different version of myself now but I still feel depressed after the breakup.
