I have been struggling…and need support (please)

28 yr old female. I suspect I might have ADHD, OCD, and maybe Autism. I have NF 1, which has higher rates of ADHD and autism. I suspect my dad had OCD, and one of his brothers had OCD. I have a history of trauma, with a counseller telling me I had PTSD.

Lately I’ve been struggling with with low self esteem, anxiety, intrusive thoughts/compulsions, and in the //past// Ive struggled with depression, self harm, disordered eating, I even tried to k*ll myself after experiencing trauma and not feeling like anyone believed me, etc.
Lately, I have been making frequent mistakes at work due to forgetfulness that have gotten me in trouble, and I have thought about hurting myself (as punishment and relief from all the spiraling).
I feel burnt out and have been struggling to take care of myself- get enough sleep at a proper time, get enough exercise, drink enough water, do housework regularly.
I was going to counseling but I now I have one session’s worth of coverage left, if that. I think my husband has benefits I could use but I feel hesitent, as I struggle to properly open up in counseling and I feel like nothing gets fully resolved. I’ve even talked to a psychiatrist on the phone about getting diagnosed with something other than anxiety but nothing came of it.
Recently I booked an appointment with my doctor at the end of October (earliest she was available) to try and get another appointment with a psychiatrist, but I feel like I can’t or shouldn’t wait that long.
I know there are steps I can take to care for myself but I fall into bad habits so easily and taking these small steps to care for myself doesn’t feel like enough.
I was on meds eariler this year but I titrated off of them after being on them for four years, because it felt like a bandaid, that wasn’t working that well. At the same time, I feel like I am making things up and I am just lazy, or a bad person.
