Could use some advice/opinions

Not the best with words so sorry if this is unorganized and kinda comes across as word vomit. I been struggling for a while and just needed a place to vent or just find a place where I can be heard. So I’m a 33 year old male I take lexapro for anxiety and amitriptyline for depression. I was started taking lexapro about 4 years ago when I was in paramedic school late one night I had a panic attack and collapsed in my kitchen. After my schooling I ended up getting a job with a volunteer fire department after 2 years I ended up quitting cause I couldn’t handle the anxiety that the job gave me.

That was about 2 years ago since then I been working full time at Home Depot trying to make the best of things and feel like I been doing ok there (even to the point where they’ve discussed making me a department head though not sure how I’d be at that or if I want that). However a lot of times I just keep thinking about how I feel like I’m a failure. Not sure if anyone can relate this or give me some tips thanks
