This is my first time posting here, but I feel like I need some encouragement from folks who know what it's like to be constantly anxious and doubting all of my decisions.

TL;DR - How do I (30F) know whether my symptoms are severe enough to need more intense help beyond therapy and medication? Has anyone been through an intensive outpatient program (around 15 hours per week of group therapy) and found it helpful?

I've struggled with anxiety, depression, and PTSD for around 10 years. This year my symptoms have been getting worse and I feel like my medication isn't working. I'm missing a lot of work because of this. My doctor switched medications a couple times, which led to me checking myself into the ER after a bad reaction to meds had me afraid I'd hurt myself. 

That was a couple weeks ago, and I've been out of work since then. I started seeing a new therapist and a psychiatrist which I think is a big step in the right direction. My psychiatrist is having me switch meds again though and I'm so anxious about the transition. I'm planning to return to work next week, but going back to work the same week as starting new meds has me feeling paralyzed with fear. I'm not suicidal, per se, but I still have suicidal thoughts if that makes sense.

While in the ER, I got a referral to an intensive outpatient program. They just called and said a space opened up. It would be 3 hours 3 days a week for 8 weeks of DBT group therapy. It's online due to covid, and I work online, so I'd be able to do it and keep my job. 

I worry that I'm not in a "bad" enough place for the program, though. What if I show up and everyone thinks I'm weak and entitled because my problems are so much more minor than theirs? I feel like I should be happy, I have everything I need. But I'm not, and that makes me feel like such an imposter.

Any advice, encouragement, tough love, etc would be greatly appreciated.
