I am deeply unhappy with my life

I, 20M, am deeply unhappy with my life. I don't know how to explain this but I have multiple health issues and all of them together have caused a lot of issues to me.

1. I am left eye blind (irreversible, lost at age of 9), right eye weak with power of -4.5

2. I have multiple vitamin deficiency

3. I have hair loss since i was 16, I have gained 40kg in 4 years, i started intermittent fasting and walking a lot but no effect of weight

4. I have clinical depression and anxiety which was treated for 15 months

5. I have stomach issues with constipation and blood from stool

6. 3 years ago i was close to hypothyroidism and didn't checked it again

7. I have high Blood pressure issues at times

8. I got no friends and i have been bullied a lot.

I have no emotional support. I have numbed out completely because my family just says you are lazy and you don't try hard enough. I don't know how to get out of this situation.

I cannot sleep properly at nights and sometimes not at all sleeping.

I have more things in my head and i cannot keep them quiet. I cannot take this pain anymore.
