Ive been feeling really lonely.?

im 16 and idk i feel empty inside sometimes i feel like crying when im trying to sleep and it takes me forever topass out. i was doing drugs in 10th grade mostly ecstacy and weed and it helped but i got kicked out i had alot of friends there but everytime things seem to be going good in my life it turns to **** and right now a regular school wont accept me so im going to a community day school i am suppose to complete 20 credits there and do some counceling but i have 3 weeks left and havent done anything if i dont get it done it time i have to stay there longer but i keep procrastinating in class and falling asleep because i cant sleep at night i dont see a point in trying anymore i think im gonna b alone and single for ever and i dont see the point in living but this isnt saying im gona commit suicide
