Seeking advice or support?

Hi. First post here I'm 20, female AUDHD have BPD and am chronically ill. I have MCAS + other unknown symptoms that I believe may be POTS. But that's not why I made this post. I'm wondering if anyone like literally ANYONE is in the same boat or can relate because I was doing super well in DBT and still am but I almost feel like I'm regressing (SI thoughts and intense urges to SH.) because of how much time I spend at home and in bed due to severe fatigue. I just feel so alone and so tired. I'm well supported by my family and I know that but my health has changed so severely in the past year and I guess I'm struggling to cope. My therapist and I are practicing radical acceptance around my health and how much it truly limits me. I'm open to advice and suggestions if at all possible please use tone tags :')
