Got my first salary and I'm afraid (3.5lpa)

Long time lurker and first time poster,

So i received my first salary of 23k yesterday. I am confused and afraid about how am i going fo manage "everything" in this.

Here are breakdown of everything:

Fix expenses:

• Rent = 5500
• SIP (3 sips) = 5000
• fd for emergency= 2000
• bike (this expense is only for 2 months) = 3500

Variable expenses:

• food = 2500-3000
• fuel = 1000-1500
• cigs = 2000~

So now im remaining with 7000 (not including variable expenses)and after next month I'll be remaining with 9000 (i plan on increasing emergency as well)

So i wanted some suggestions if this breakdown is good or should i change anything?
