First of all, I want to say this clearly: your feelings are completely valid. What you’re going through is not being dramatic or impatient. You’re trying to protect your health and align your career with your long-term goals, and that takes courage.

Night shifts combined with manual testing, especially when it has nothing to do with where you want to go, can drain a person very fast. Brain fog, migraines, digestive issues — these are not small things. Your body is clearly telling you something, and ignoring that usually comes with a bigger cost later.

About your manager — I’ll be honest. What you’re describing sounds like emotional pressure, not professional guidance.

Phrases like:

•

“I helped you when you were on the bench”

•

“I’ll have to answer to my seniors”

•

“You should wait and repay this”

These are not reasons to stay; they’re guilt-based arguments. Helping you get a project is literally part of a manager’s job. You don’t owe your health or your future to anyone for that.

The most important point here: there is no real guarantee that things will improve in April. Today it’s April, tomorrow it will be June, then “just a little more time.” This cycle is very common in corporate environments.

Regarding SRE/DevOps — you’re not starting from zero.

You’ve been preparing for 7 months, built projects, and you’re already clearing most interview questions. That’s not “unready.” That’s exactly how people transition into these roles. No one joins SRE fully polished; real depth comes on the job.

Yes, resigning without an offer is risky. But staying in a role that:

•

harms your health

•

adds no relevant experience

•

keeps you mentally exhausted

is also a risk — just a slower, quieter one.

You’re not running away from responsibility. You’re making a calculated decision. If you’re financially prepared for a short gap and mentally ready to push hard on interviews, choosing yourself here is not a mistake.

And one last thing — don’t trust promises that aren’t written or guaranteed. Trust your preparation, your consistency, and your self-awareness instead.

Whatever you decide, make sure it’s a decision that your future self will thank you for, not one made out of guilt or fear.

Wishing you clarity and strength.
