Do I qualify at 27? number of health issues

Hello
I've been going back and forth about whether I should apply to disability for a while now.

I've been diagnosed with a genetic disorder that causes tumors to grow in soft tissues- luckily I've had the pre cancerous ones removed however I have a pituitary brain tumor that still causes migraines and hormonal imbalances even on medication. I also have fibromyalgia, PTSD, bipolar depression and anxiety. Not to mention I have spinal stenosis and recently slipped a disc.

I currently work full time but I usually have to call out a couple times a week due to pain and extreme mental and physical fatigue since I cannot recover as quickly as a healthy individual.
I'm really good at just putting a smile on my face and forcing myself to get through the week so a lot of people don't know I'm in pain, suicidal, panicking etc. But it's always with extreme discomfort and I often make mistakes and am very forgetful. I have worked very physical jobs to sedentary jobs to something in between (currently) but nothing helps. I always feel guilty about calling out and I know soon I will be out of sick time because of this.

I love my job and would love to work a couple days a week but I'm not sure if I would qualify for disability...im hesitant as well because at 27yrs old I'm worried people will judge. Think I'm lazy or something. :(
Sorry for the heavy text...help? Thoughts??
Thanks!
